X-Band 1000W GaN Solid-State Power Amplifier PCBA
SAMP090950-60P · 9.0–9.5 GHz · Pulsed · WR90 Waveguide · Military-Grade · Superb Automation
Product Overview
The SAMP090950-60P is a military-grade X-band pulsed solid-state power amplifier (SSPA) operating from 9.0 to 9.5 GHz, capable of delivering 1000W peak output power (60 dBm). Built with the latest GaN HEMT (Gallium Nitride High Electron Mobility Transistor) technology in a Class AB architecture, this compact module replaces traditional vacuum-tube TWT amplifiers — offering instant-on operation, longer service life, superior linearity, and intelligent remote control.
Designed as the "pulse heart" of modern radar transmitters, electronic warfare (EW) jamming systems, and high-power RF test benches, the SAMP090950-60P supports ultra-flexible pulse widths from 200 ns to 200 μs at duty cycles up to 20%. It maintains rated performance across the full military temperature range of -40°C to +60°C case temperature.
Superb Automation provides full turnkey PCBA assembly for this SSPA module — including GaN device mounting, waveguide interface integration, conformal coating, and functional test — at our ISO 9001 certified 5,000m² SMT facility.

Interface & Connectors
| Connector | Type | Designation | Description |
|---|
| RF Input | SMA Female | J1 | 50Ω, +5 dBm nominal drive level |
| RF Output | WR90 Waveguide | J2 | Low-loss high-power transmission; eliminates coaxial connector breakdown at kW levels |
| DC Power | Hybrid D-Sub 7-Pin Male (7W2) | J3 | Dual supply: +40V (A1-A2) + +28V (pins 1-2 / 4-5), each with dedicated ground return |
| Control | J30J-15ZKP | J4 | RS485 (A/B), temperature monitor (10mV/°C, 500mV offset), PA Enable (TTL 0/3.3V) |
⚠️ Power Sequencing Note: The SAMP090950-60P requires dual DC supplies — +40V for the main GaN power stage and +28V for internal driver/control circuits. Each rail has a dedicated ground return. Proper power sequencing must be observed: apply +28V first, then +40V; remove in reverse order.
Built-in Control & Protection
| Function | Detail |
|---|
| RS485 Serial Interface | Remote monitoring (temperature, status) and control (attenuator setting, PA enable) via standard Modbus-compatible protocol |
| PA Enable (TTL) | 0/3.3V logic; internally pulled low (default OFF); high = amplifier enabled. Supports pulse synchronization up to 20% duty |
| Temperature Monitor | Analog voltage output @ 10mV/°C with 500mV offset (e.g., 0.75V = 25°C) |
| Built-in Protection | Over-temperature, over-voltage, over-current, and high-VSWR protection with auto-shutdown |
| Digital Attenuator | 20 dB range, 1 dB steps — adjust output power via RS485 without external attenuators |
