Features a GaN-based design delivering stable 52–55dB gain across the full 700–1020MHz operating band, ensuring consistent high-efficiency performance over a wide instantaneous bandwidth.
Delivers high-precision output power of 50±0.5dBm, paired with dual forward/reverse power detection (3.5V @ 50dBm, 0.08V/dB step)
Flexible EN enable control (active low) with 5V/10kΩ pull-up, integrated protection functions including over-temperature (95℃ shutdown/75℃ restart) and VSWR alarm
Optimized RF performance with input/output VSWR ≤1.4, maximum input level of +3dBm, and dedicated SMA input/N-type output connectors
Compact 165×55×24.5mm form factor, 28V tri-pin power supply, and comprehensive monitoring functions (temperature detection, power monitor, alarm status)
UZI-GRQ-700-1020M-100W-GaN-16555-EN-CPU-VFA
Test at an output power of 40dBm. To protect the power amplifier, prohibit testing the VSWR protection function at an output power exceeding 47dBm.
When the cable is connected properly, the voltage of Pin 4 (VSWR alarm pin) shall be low level (0V).
When the output cable is disconnected, the power amplifier output shall shut down for protection. The voltage of Pin 2 (output power detection pin) shall be low level (0V), and the voltage of Pin 4 (VSWR alarm pin) shall be high level (2.7–3.3V) simultaneously.
During a VSWR alarm (with output shut down and output cable disconnected), keep the power amplifier powered on and reconnect the output cable. Then activate the power amplifier via the external EN signal. The voltage of Pin 2 shall switch to high level, and the voltage of Pin 4 shall return to low level (0V) simultaneously.
During a VSWR alarm (with output shut down and output cable disconnected), reconnect the output cable. Then power off the power amplifier and power it on again. The voltage of Pin 2 shall be high level, and the voltage of Pin 4 shall be low level (0V) simultaneously.
Single-tone signal test
Over-temperature protection: Hardware-controlled with fixed thresholds. Shutdown at +95℃; automatic restart at 75℃.
The power amplifier has no ALC control function.
The power amplifier is equipped with an isolator and features an N-type output connector.
The model suffix VFA indicates that the power amplifier is integrated with VSWR alarm function.
