Product details
Overview
TRF370317IRGET from Texas Instruments is a silicon germanium direct quadrature modulator converting complex baseband I/Q signals to RF output across 0.4–4 GHz. It delivers 12 dBm P1dB, 26.5 dBm OIP3, –163 dBm/Hz noise floor, and –40 dBm unadjusted carrier feedthrough at 1960 MHz. It serves as the final RF upconversion stage in cellular base station transceivers requiring high linearity and low distortion.
For engineers reviewing the TRF370317IRGET datasheet, TRF370317IRGET pinout, TRF370317IRGET application, or TRF370317IRGET equivalent, key selection criteria include unadjusted sideband suppression (–50 dBc), LO input power range (–5 to 12 dBm), 1.7-V baseband common-mode voltage requirement, and QFN-24 package thermal resistance (29.4 °C/W).
Technical Context
The TRF370317IRGET implements a double-balanced mixer architecture with integrated differential-to-single-ended RF output stage capable of driving 50-Ω loads directly. Its baseband inputs (BBIP/BBIN/BBQP/BBQN) require precise 1.7-V DC common-mode bias for optimal linearity and sideband suppression.
LO interface accepts single-ended 50-Ω input (LOP) with on-chip termination for LON; RF output (RF_OUT) is single-ended and AC-coupled. Performance is specified across –40°C to +85°C ambient, with supply voltage tolerance from 4.5 V to 5.5 V and total supply current of 245 mA typical at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.4 GHz to 4 GHz RF output - supports WCDMA, LTE, WiMAX, and TD-SCDMA bands without external tuning. |
| P1dB | 12 dBm at 1960/2140 MHz - enables direct drive of PA stages without intermediate gain stages in macro/micro base stations. |
| OIP3 | 26.5 dBm at 1960 MHz - ensures >74 dBc ACPR for single-carrier WCDMA at –8 dBm channel power. |
| Noise Floor | –163 dBm/Hz at ≥13 MHz offset - minimizes reciprocal mixing in dense RF environments. |
| Carrier Feedthrough | –40 dBm unadjusted at 1960 MHz - reduces need for external calibration circuitry in production test. |
| Sideband Suppression | –50 dBc unadjusted at 1960/2140 MHz - maintains EVM <0.43% for EDGE and LTE signals. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard telecom DC-DC rails and simplifies power design. |
Pinout & Package
TRF370317IRGET uses a 4-mm × 4-mm, 24-pin QFN package (RGE) with exposed thermal pad. Pin 1 is located at top-left corner per TI SLWS209B revision January 2010; package meets JEDEC MO-220 standards and supports reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BBIP / BBIN | In-phase differential baseband input | Accepts 1.7-V CM, 98-mVrms SE signal; impedance ~5 kΩ || 3 pF - requires external AC coupling and CM bias network. |
| BBQP / BBQN | Quadrature-phase differential baseband input | Matches BBIP/BBIN in bandwidth (350 MHz) and CM requirement - critical for IQ imbalance control. |
| LOP / LON | Differential local oscillator input | LOP accepts –5 to 12 dBm single-ended drive; LON internally terminated to 50 Ω - eliminates external termination resistor. |
| RF_OUT | Single-ended RF output | Drives 50-Ω load directly; AC-coupled via 100-pF capacitor - no external matching required below 2.5 GHz. |
| VCC (Pins 18, 24) | Power supply | Two dedicated 4.5–5.5 V supply pins - decoupling required per TI layout guidelines to maintain PSRR >50 dB. |
| GND (Pins 1,2,5,8,11,12,14,17,19,20,23) | Ground reference | 11 ground pins including thermal pad - mandatory for thermal dissipation (RθJA = 29.4 °C/W) and RF return path integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Direct quadrature modulation | Eliminates image-reject filtering and IF SAW filters - reduces BOM count and board area in compact transceivers. |
| Integrated RF output amplifier | Drives 50-Ω load without external components - simplifies layout and improves repeatability across production units. |
| 1.7-V baseband common-mode voltage | Optimizes linearity and sideband suppression - mandates precise biasing but enables compatibility with 1.8-V DACs (e.g., DAC5687). |
| Low-noise SiGe process | –163 dBm/Hz noise floor at 13-MHz offset - preserves SNR in wideband OFDM systems like LTE and WiMAX. |
| Wide LO input power range | –5 dBm to 12 dBm - accommodates both low-power PLL synthesizers and high-output VCOs without attenuators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadrature modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5375-05ACPZ-R7 | Wider baseband BW (2 GHz), higher supply current (320 mA), no integrated RF amp - requires external driver. | Better suited for wideband radar or broadband instrumentation where >500-MHz I/Q bandwidth is needed. | Select ADL5375-05 if baseband bandwidth >1 GHz is required; TRF370317IRGET preferred for telecom with integrated output drive. |
| MAX2022ETX+T | Lower frequency range (400–3000 MHz), higher P1dB (14 dBm), 3.3-V operation - incompatible with 5-V telecom rails. | Targets portable infrastructure and small-cell radios where lower voltage and smaller form factor are prioritized. | Choose MAX2022ETX+T for 3.3-V designs or sub-3-GHz bands; TRF370317IRGET remains optimal for full 4-GHz coverage and 5-V systems. |
Compared with ADL5375-05ACPZ-R7 and MAX2022ETX+T, the TRF370317IRGET uniquely balances 4-GHz RF coverage, integrated 50-Ω drive capability, and telecom-grade linearity - making it the most suitable choice for macro base station transceivers requiring minimal external components and proven WCDMA/LTE performance.

FAQ
What is the recommended baseband common-mode voltage for TRF370317IRGET?
The TRF370317IRGET requires a precise 1.7-V DC common-mode voltage on all four baseband inputs (BBIP, BBIN, BBQP, BBQN) to achieve specified linearity, sideband suppression, and carrier feedthrough. Deviation beyond ±50 mV degrades OIP3 by >3 dB and increases EVM - TI recommends using a dedicated low-noise 1.7-V reference or resistive divider with bypass capacitors.
Does TRF370317IRGET support single-ended or differential LO drive?
The TRF370317IRGET accepts single-ended LO drive on LOP (pin 3) with internal 50-Ω termination on LON (pin 4). Differential LO is not supported; applying differential signals risks imbalance and degraded sideband suppression. TI specifies LO input power range as –5 dBm to 12 dBm single-ended into 50 Ω.
What is the thermal resistance and maximum junction temperature of TRF370317IRGET?
The TRF370317IRGET has RθJA = 29.4 °C/W (high-K board, still air) and RθJC = 18.6 °C/W. Its absolute maximum virtual junction temperature is 150°C, with recommended operating ambient range of –40°C to +85°C. Maintaining PCB copper area under the exposed thermal pad is essential to sustain 245 mA supply current without exceeding TJ.
Can TRF370317IRGET be used in 5G NR sub-6 GHz applications?
The TRF370317IRGET operates up to 4 GHz and delivers –72 dBc ACPR for 2-carrier WCDMA - performance validated through 3.5 GHz. While not characterized for 5G NR OFDM waveforms per 3GPP 38.104, its 350-MHz baseband bandwidth and 26.5 dBm OIP3 support limited 5G FR1 use cases below 3.8 GHz with appropriate digital predistortion; TI does not guarantee 5G NR compliance.
How many ground pins does TRF370317IRGET have, and why are they critical?
The TRF370317IRGET has 11 dedicated ground pins (pins 1,2,5,8,11,12,14,17,19,20,23) plus an exposed thermal pad. These provide low-inductance RF return paths, minimize ground bounce during fast switching, and enable effective heat dissipation - critical for maintaining –163 dBm/Hz noise floor and preventing thermal drift in P1dB/OIP3 over temperature.
