| Parameter | Specification |
|---|---|
| Frequency Range | 3400 MHz ~ 3800 MHz (Precisely covers 5G NR n78 core band, compatible with 4G TDD-LTE 3.5GHz band) |
| Peak Output Power | 16W Continuous Wave (CW), in Doherty Configuration (42dBm typical, at 28V supply, pulsed CW measurement) |
| Typical Power Gain | 32.5 dB (at 28V supply, 40dBm peak output, 3600MHz, CW signal) |
| Typical Drain Efficiency | 24.3% (at 10dB OBO, 1-carrier W-CDMA signal, PAR=7.2dB, 3600MHz) |
| Supply Voltage | 26V/28V nominal, Maximum Rated Drain-Source Breakdown Voltage 65V |
| Quiescent Current | 38 mA (carrier path), independent biasing for peaking path (VGSq(peak)=VGSq(carrier)-0.5V) |
| Package Type | LGA-7x7-20-2, 7×7mm leadless thermal enhanced package with exposed thermal pad, 20 terminals |
| Port Characteristics | Internally matched to 50Ω input/output, no external matching required, simplifying RF PCB design |
| Architecture | 3-stage fully integrated Doherty with built-in input splitter, output combiner, carrier/peaking amplifier paths and driver stages |
