NXP Semiconductors CLF1G0035-100PU

Overview

CLF1G0035-100PU from NXP Semiconductors is a 100 W broadband GaN HEMT RF power transistor operating from DC to 3.5 GHz, rated for 50 V drain-source voltage and delivering 14.4 dB typical pulsed power gain at 2600 MHz with 54.4% drain efficiency. It serves as a high-power RF amplifier stage in base station transmitters and radar front-ends.

For engineers reviewing the CLF1G0035-100PU datasheet, CLF1G0035-100PU pinout, CLF1G0035-100PU application, or CLF1G0035-100PU equivalent, key selection criteria include its 100 W P_L capability at 2.5–3.0 GHz, VSWR = 10:1 ruggedness under class-AB operation, thermally enhanced flanged ceramic SOT1228A package, and GaN-based high-voltage RF performance.

Technical Context

This GaN HEMT operates in class-AB configuration with fixed 330 mA quiescent drain current and 50 V drain bias, optimized for broadband RF amplification up to 3.5 GHz. Its dual-gate/dual-drain structure supports balanced or push-pull configurations while maintaining thermal stability via flange-mounted case dissipation.

Designed for pulsed and CW RF applications, it delivers consistent 100 W output across 2500–3000 MHz in both 1-tone pulsed (tp = 100 µs, δ = 10%) and 2-tone CW (Δf = 100 kHz) modes, with third-order intermodulation distortion as low as −43 dBc at 2600 MHz.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the CLF1G0035-100PU?

The CLF1G0035-100PU is specified for operation from DC to 3.5 GHz, with verified RF performance up to 3000 MHz in both CW and pulsed modes. Its usable bandwidth covers key bands including 2500–2700 MHz LTE, 2.4–2.5 GHz public safety, and L-band radar frequencies.

Does the CLF1G0035-100PU require external gate bias circuitry?

Yes, the CLF1G0035-100PU requires an external negative gate bias (typically −7 V to −3 V) and current-limiting gate resistor to establish the 330 mA quiescent drain current. The device does not integrate bias regulation, so discrete or IC-based gate controllers must be used per the application note AN11852.

Is the flange of the CLF1G0035-100PU electrically isolated?

No-the flange of the CLF1G0035-100PU is internally connected to Pin 5 (source), as confirmed in the pinning table and package outline. This establishes a low-inductance, low-thermal-resistance path to the heatsink and must be treated as part of the source reference plane in layout.

What is the recommended thermal interface material for CLF1G0035-100PU?

NXP recommends using a thermally conductive, electrically insulating interface material such as Bergquist Sil-Pad 2000 or Parker Chomerics Thermasil 300 between the CLF1G0035-100PU flange and heatsink. Minimum thermal resistance target is 0.25 K/W to maintain T_j ≤ 200 °C at full 100 W output.

Can CLF1G0035-100PU replace CLF1G0035S-100PU in existing designs?

No-CLF1G0035-100PU (SOT1228A) has a flanged package with two mounting holes, while CLF1G0035S-100PU (SOT1228B) is earless and lacks mounting holes. Mechanical fit, thermal path, and PCB footprint differ; direct substitution requires board redesign and thermal validation.
