NXP Semiconductors CLF1G0035-200P

Overview

CLF1G0035-200P from Ampleon is a 200 W, DC–3.5 GHz GaN HEMT RF power transistor in a flanged ceramic SOT1228A package, rated for 50 V drain-source operation with 47–58 % drain efficiency and 9–11 dB power gain in CW broadband amplification at 1.7–2.3 GHz. It delivers rugged 10:1 VSWR tolerance and thermal resistance of 0.52 K/W for high-reliability infrastructure transmitters.

For engineers reviewing the CLF1G0035-200P datasheet, CLF1G0035-200P pinout, CLF1G0035-200P application, or CLF1G0035-200P equivalent, this page provides verified RF performance data, thermal characteristics, gate/drain/source terminal mapping, ruggedness validation under mismatched loads, and direct alternatives for cellular base station, radar, and EMC test amplifier designs.

Technical Context

This GaN HEMT operates in class-AB broadband configuration with dual-gate (gate1/gate2) and dual-drain (drain1/drain2) topology optimized for symmetrical push-pull or balanced amplifier layouts. Its 50 V operation enables high-power density while maintaining stable gain flatness across 1.7–2.3 GHz CW bands.

Thermal design leverages a flanged ceramic package with two mounting holes and case temperature monitoring capability; junction-to-case thermal resistance is specified at 0.52 K/W under 220 W dissipation, enabling high-power continuous operation when heatsinked to ≤85 °C case temperature.

FAQ

What is the maximum continuous drain current rating for CLF1G0035-200P?

The CLF1G0035-200P does not specify a maximum continuous drain current in its datasheet; instead, it defines operational limits via drain-source voltage (150 V max), junction temperature (250 °C max), and thermal resistance (0.52 K/W). At 50 V operation and 200 W output, typical quiescent drain current is 300 mA in CW mode and 600 mA in 2-tone mode-both well within safe SOA boundaries defined by V_DS, T_j, and power dissipation limits. CLF1G0035-200P relies on thermal management rather than current limiting for safe operation.

Does CLF1G0035-200P require external gate protection diodes?

Yes, CLF1G0035-200P requires external gate protection due to its ±8 V gate-source voltage limit and ESD sensitivity (HBM Class 1B). The datasheet recommends series gate resistors (RG = 5 Ω typical) and clamp diodes between gate and source to prevent damage from transient overvoltage or ESD events. CLF1G0035-200P lacks integrated gate protection, so discrete Zener or TVS diodes rated for −8 V to +3 V must be placed within 2 mm of each gate terminal (gate1 and gate2) in the layout.

Can CLF1G0035-200P be used in Doherty amplifier configurations?

Yes, CLF1G0035-200P is suitable for Doherty configurations due to its dual-gate (gate1/gate2) and dual-drain (drain1/drain2) structure, which supports carrier/peaking path separation. Application note AN11130 describes bias module implementation for GaN HEMT amplifiers, and measured load-pull data (Table 12) provides Z_L values optimized for both maximum power and efficiency-key for Doherty tuning. CLF1G0035-200P achieves >50 % efficiency at back-off in 2.3 GHz CW tests, confirming Doherty compatibility.

What is the recommended minimum gate-source voltage for reliable turn-on of CLF1G0035-200P?

The CLF1G0035-200P has a gate-source threshold voltage (V_GS(th)) ranging from −2.4 V to −1.3 V (typ −2.0 V) at V_DS = 0.1 V and I_DS = 24 mA. For reliable enhancement-mode turn-on in class-AB operation, a gate bias of −2.5 V to −3.0 V is recommended to ensure consistent I_DQ = 300–600 mA across temperature and unit variation. CLF1G0035-200P must be driven with negative gate voltage relative to source; positive gate voltage will cause irreversible damage.

Is CLF1G0035-200P compatible with standard FR4 PCBs for RF layout?

CLF1G0035-200P can be mounted on FR4, but its 200 W RF output demands rigorous RF layout practices: thick copper (≥3 oz), thermal vias under the flange (≥20× 0.3 mm diameter), coplanar waveguide routing, and precise 50 Ω microstrip impedance control. The SOT1228A package's flange must be soldered to a solid ground plane; FR4's limited thermal conductivity (0.3 W/m·K) necessitates external heatsinking. CLF1G0035-200P is typically deployed on metal-core or IMS substrates in production-FR4 is acceptable only for lab evaluation with derated power.
