Product details
Overview
T7024-PGP 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, 2.1 dB typical noise figure (QFN20), and ramp-controlled PA gain with 60 dB control range - optimized for TDMA systems requiring compact RF front-end integration with minimal external components.
For engineers reviewing the T7024-PGP datasheet, T7024-PGP pinout, T7024-PGP application, or T7024-PGP equivalent, this device supports critical design tasks including Bluetooth Class 2/3 transceiver front-end implementation, low-power ISM-band wireless modules, and integrated T/R switching with external PIN diode biasing - all under single 3-V supply operation.
Technical Context
The T7024-PGP implements a fully integrated RF front-end architecture where the PA operates across 2.4–2.5 GHz with 30 dB typical power gain and 35% typical power-added efficiency (QFN20); the LNA provides 16 dB typical gain and 2.1 dB typical NF in the same band. Control logic decodes PU, RX_ON, and RAMP inputs to coordinate PA/LNA activation and ramp-scheduled output power scaling.
RAMP voltage (0.1–1.83 V) directly modulates PA gain over 60 dB range while maintaining stable output matching (VSWR < 1.5:1 at PA input/output). The T/R switch driver supplies programmable current (up to 19 mA) via external resistor on R_SWITCH, enabling precise biasing of external PIN diodes without additional drivers.

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 |
|---|---|---|---|
| SKY65111-348LF | Higher Pout (25 dBm), but 3.3 V only; no ramp control - requires external DAC for power adjustment. | Optimized for higher-output access points; lacks integrated LNA and T/R driver. | Select when >23 dBm output is mandatory and LNA can be implemented separately. |
| MAX2643ETE+ | 2.4–2.5 GHz LNA-only (NF = 2.0 dB), no PA or switch driver; 5-pin SOT23 package. | Requires discrete PA and switch ICs - increases BOM and layout complexity. | Select only if LNA performance is primary concern and system already includes PA/switch functions. |
Compared with SKY65111-348LF and MAX2643ETE+, the T7024-PGP uniquely integrates PA, LNA, and T/R driver in one QFN20 package with analog ramp control - reducing bill-of-materials by 8+ components and enabling single-supply, space-constrained Bluetooth/ISM designs without sacrificing RF performance.

FAQ
What is the maximum recommended supply voltage for the T7024-PGP PA section?
The T7024-PGP PA section supports a maximum supply voltage of 4.6 V on pins V1_PA, V2_PA, and V3_PA_OUT. Exceeding this value risks permanent damage per absolute maximum ratings. For reliable operation at 23 dBm output, 3.0 V is the typical nominal supply - delivering optimal PAE (35%) and thermal performance in the QFN20 package.
Does the T7024-PGP require external matching networks for 50 Ω system integration?
Yes, the T7024-PGP requires external matching networks at both PA_IN and LNA_IN ports to achieve 50 Ω impedance transformation, as specified in Figures 20–25 of the datasheet. The PA output (V3_PA_OUT) also requires an external inductor and harmonic termination network. However, output VSWR remains <1.5:1 across the 2.4–2.5 GHz band when properly matched - simplifying validation.
How does the RAMP pin function in the T7024-PGP, and what voltage range controls full gain range?
The RAMP pin on the T7024-PGP is an analog input that linearly controls PA gain from –40 dB to +33 dB across 0.1 V to 1.83 V. At VRAMP = 0.1 V, PA gain is minimized (–40 dB); at VRAMP = 1.75 V, gain reaches maximum (33 dB). This 60 dB range enables precise closed-loop transmit power control without digital attenuation or external DACs.
Can the T7024-PGP operate with separate 2.7 V and 3.3 V supplies for LNA and PA sections?
Yes, the T7024-PGP supports independent supplies: VS_LNA accepts 2.7–5.5 V, while V1_PA/V2_PA/V3_PA_OUT accept 2.7–4.6 V. This allows optimizing LNA noise performance at 2.7 V and PA efficiency at 3.3 V. However, all supplies must share a common ground, and simultaneous operation requires coordinated PU/RX_ON timing per the control logic table on page 5.
What is the thermal resistance (RthJA) of the T7024-PGP QFN20 package, and how does it impact continuous 23 dBm operation?
The T7024-PGP QFN20 package has a junction-to-ambient thermal resistance (RthJA) of 27 K/W when the thermal slug is soldered to PCB copper. At 23 dBm output (200 mW), 165 mA supply current, and 3.0 V supply, power dissipation is ~330 mW. With RthJA = 27 K/W, junction temperature rise is ~8.9°C above ambient - well within the 150°C max rating, enabling safe continuous operation at full output up to +85°C ambient.
