| Gain | 50 ± 2 dB Max. |
| Power Supply | +28 V DC / ≤3.8 A |
The BT-PA398-35M8W-RS485 is a TETRA RF Power Amplifier Module designed for the 380–415 MHz frequency range. It provides up to 39 ± 1 dBm output power with a maximum gain of 50 ± 2 dB, providing RF amplification within wireless communication equipment.
The module amplifies RF signals within the 380–415 MHz band and supports adjustable gain, Automatic Level Control (ALC), and RF performance monitoring. Its RF interface uses an SMA connector, while an RS485 interface provides configuration, status query, alarm, and monitoring functions.
The module combines high RF gain, adjustable gain control, ALC, RS485 monitoring, and protection functions in a compact 200 × 140 × 28 mm package. The module also supports temperature, VSWR, power, and PA fault monitoring for integration into wireless communication equipment.
Wide 35 MHz Operating Band
Designed for RF amplification across the 380–415 MHz frequency range, with a 35 MHz bandwidth.
Up to 39 ± 1 dBm Output Power
Provides maximum output power of 39 ± 1 dBm, equivalent to approximately 8 W, for RF system integration.
Flexible Gain Control
Maximum gain reaches 50 ± 2 dB, with an adjustable gain range of at least 25 dB and gain adjustment steps of ≤1 dB.
Integrated Signal Management
The module supports ALC ≥10 dB and RS485-based monitoring of forward power, reverse power, temperature, VSWR, ALC and attenuation.
Built-In RF Protection
The module supports over-temperature, over-power, VSWR and PA fault alarms. At temperatures above 85°C, the PA switches off and automatically resumes operation below 65°C.
Remote Setup & Status Query
RS485 supports PA ON/OFF, module address, ALC and ATT configuration, together with operating-status and alarm queries.
