Product details
Overview
T7024-PGPM from Atmel is a monolithic SiGe 2.4–2.5 GHz Bluetooth®/ISM transmit/receive front-end IC integrating power amplifier (PA), low-noise amplifier (LNA), and T/R switch driver in a single QFN20 package. It delivers 23 dBm typical saturated output power with 35% typical power-added efficiency, 2.1 dB typical noise figure, and ramp-controlled gain adjustment across 60 dB range - optimized for TDMA systems requiring integrated RF front-end functionality with minimal external components.
For engineers reviewing the T7024-PGPM datasheet, T7024-PGPM pinout, T7024-PGPM application, or T7024-PGPM equivalent, this device supports rapid integration into compact 2.4 GHz wireless transceivers where supply current optimization (8 mA RX, 165 mA TX), standby leakage (10 µA), and dual-package compatibility (QFN20 vs PSSO20) are critical selection criteria.
Technical Context
The T7024-PGPM implements a fully integrated SiGe RF front-end architecture with independent bias control paths for PA (V1_PA/V2_PA/V3_PA_OUT) and LNA (VS_LNA), enabling simultaneous operation or mode-selectable isolation. Its ramp-controlled PA gain (0.1–1.83 V on RAMP pin) provides precise linear power control without external VS switching transistors.
Control logic uses active-high PU and RX_ON signals to configure five operational modes - including dedicated TX, RX, standby, and special-purpose combinations - while the SWITCH_OUT pin drives external PIN diodes via resistor-programmed current (1–19 mA) referenced to R_SWITCH to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2.4–2.5 GHz - matches Bluetooth Classic and ISM band requirements with no external tuning needed. |
| Saturation Output Power | 23 dBm typical - sufficient for Class 1.5/Class 2 Bluetooth links with margin for PCB losses. |
| Noise Figure | 2.1 dB typical (QFN20) - enables high-sensitivity RX performance in low-SNR environments. |
| Power-added Efficiency | 35% typical (QFN20) - reduces thermal load and extends battery life in portable devices. |
| Supply Current (TX) | 165 mA typical at 3 V - lower than PSSO20 variant, supporting thermally constrained layouts. |

Pinout & Package
Package: QFN20 (5 mm × 5 mm, 0.65 mm pitch, 3.1 mm × 3.1 mm exposed thermal slug).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LNA_OUT | LNA output | Delivers amplified 2.4–2.5 GHz RX signal to baseband IC; requires external matching network per Figure 10-8. |
| RX_ON | Receive enable | Active-high logic input controlling LNA activation and T/R switch state; voltage level also adjusts LNA gain (Figure 9-16). |
| PU | Power-up enable | Global active-high enable for internal regulators and bias circuits; must be asserted before RAMP or RX_ON. |
| R_SWITCH | PIN diode current set | Resistor-to-GND sets programmable T/R switch driver current (1–19 mA); determines antenna isolation and switching speed. |
| SWITCH_OUT | T/R switch driver output | Current-source output driving external PIN diode; sinks current when RX_ON = 1 and PU = 1. |
| GND | Ground reference | 14 pins total (including thermal slug); all must be connected to low-impedance ground plane for RF stability and thermal dissipation. |
| V3_PA_OUT | PA output matching node | Three parallel pins connect to external inductor/matching network for PA output; handles high RF current at 23 dBm. |
| V2_PA | PA VDD2 supply | Dual inductor-connected supply pins provide decoupled biasing for PA stages; improves PSRR and harmonic suppression. |
| V1_PA | PA VDD1 supply | Primary PA supply input; requires local 3.3 µF + 100 nF decoupling per Figure 10-1. |
| PA_IN | PA input | Accepts 0 dBm nominal RF drive from transceiver; input matching optimized for 50 Ω source impedance. |
| RAMP | PA gain control | Analog voltage input (0.1–1.83 V) setting PA gain linearly; eliminates need for digital DAC or external ramp generator. |
| VS_LNA | LNA supply | Independent 2.7–5.5 V supply for LNA; enables flexible rail selection and noise isolation from PA supplies. |
| LNA_IN | LNA input | RF input port for antenna or filter output; input VSWR < 2:1 ensures stable matching across band. |
Key Features
| Feature | Design Value |
|---|---|
| Ramp-controlled PA output power | Enables precise analog power control (0.1–1.83 V) without external DAC or microcontroller GPIO sequencing. |
| Integrated T/R switch driver | Eliminates discrete switch IC and associated control logic; resistor-programmed current simplifies antenna path design. |
| Low-quiescent-current standby mode | 10 µA draw allows >1-year battery life in intermittent-monitoring IoT sensors using Bluetooth LE extensions. |
| Thermally enhanced QFN20 package | 27 K/W junction-to-ambient thermal resistance (slug soldered) supports continuous 23 dBm operation at +85°C ambient. |
| Single 3-V supply operation | Reduces BOM count by eliminating separate LNA/PA rails; VS_LNA and PA supplies share same 3 V source if desired. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2.4 GHz front-end applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| T7024-TRSY | PSSO20 package; 190 mA TX current; 19 K/W thermal resistance; Pb-free tube packaging. | Better thermal performance but larger footprint; suited for higher-duty-cycle or convection-cooled designs. | Select T7024-TRSY when board space permits and thermal headroom is prioritized over miniaturization. |
| SKY65111-301 | 2.4–2.5 GHz FEM with 20 dBm Pout, 30% PAE, integrated filtering; 16-pin QFN; no ramp control. | Fixed-gain PA; requires external MCU-controlled GPIO for power level changes; lacks LNA gain adjust via RX_ON. | Choose SKY65111-301 only if system-level digital control is preferred and 3 dB lower output power is acceptable. |
Compared with T7024-TRSY, T7024-PGPM trades 25 mA higher TX current for 30% smaller footprint and halogen-free tape-and-reel logistics; versus SKY65111-301, it offers analog ramp control and LNA gain tuning but requires more external matching components.

FAQ
What is the maximum operating temperature for the T7024-PGPM?
The T7024-PGPM has a maximum junction temperature of 150°C and an ambient operating range of –25°C to +85°C. Its QFN20 package achieves 27 K/W junction-to-ambient thermal resistance when the exposed slug is properly soldered to a thermal pad on the PCB, enabling sustained 23 dBm output at +85°C ambient. Derating curves in Figure 9-15 confirm stable Pout across temperature with VRAMP control.
Does the T7024-PGPM require external matching components?
Yes, the T7024-PGPM requires external matching networks on both PA_IN and V3_PA_OUT for optimal 50 Ω input/output impedance, as specified in Figures 10-1 and 10-4. LNA_IN and LNA_OUT also require external matching (Figure 10-6 and 10-8) to achieve <2:1 VSWR and specified NF/gain. The "few external components" feature refers to elimination of discrete PA/LNA/switch ICs-not passive matching elements.
How does the RAMP pin control output power on the T7024-PGPM?
The RAMP pin accepts an analog voltage (0.1–1.83 V) that linearly controls PA gain from –40 dB to +33 dB, enabling continuous output power adjustment without digital interface. At VRAMP = 1.75 V, T7024-PGPM delivers 23 dBm saturated output; at VRAMP = 0.1 V, PA is effectively disabled. This analog ramp replaces external DACs or PWM-based control, simplifying timing-critical Bluetooth packet power ramping.
Can the T7024-PGPM operate with a single 3.0 V supply for both PA and LNA sections?
Yes, the T7024-PGPM supports single 3.0 V operation across all supply pins: V1_PA/V2_PA/V3_PA_OUT (2.7–4.6 V range) and VS_LNA (2.7–5.5 V range). Using one shared 3 V rail reduces system BOM and simplifies power design, though independent regulation may improve noise isolation in sensitive RX applications. Electrical characteristics in Section 7 are tested at VS = 3.0 V.
What is the function of the R_SWITCH and SWITCH_OUT pins on the T7024-PGPM?
R_SWITCH is a reference terminal tied to an external resistor (1 Ω to 33 kΩ) to ground, setting the current sourced by SWITCH_OUT. SWITCH_OUT is a current-output driver pin that sinks programmable current (1–19 mA) to control external PIN diodes in T/R antenna switching. This eliminates need for discrete switch drivers and allows precise current tuning for optimal antenna isolation and switching speed.
