Integrated B8 40W Power Amplifier Module for RF Systems
ZD-PA-B8-40W
This Integrated B8 40W Power Amplifier Module is tailored for various RF systems. Its transmit channel covers 925-960MHz with 46±1dBm output power, supporting ALC and ≥20dB gain adjustment in 1dB steps. The receive channel works at 880-915MHz, equipped with LNA and noise figure ≤1.8dB. Both channels feature in-band fluctuation ≤2.0dB and VSWR ≤1.5. Adopting DC +28V power supply, it is fitted with MCX and SMA ports as well as RS485 monitoring interface. It operates stably within -25℃ to +55℃. Compact and reliable, this module is a great choice for wireless signal transceiving.
Quantity:
This B8 40W integrated power amplifier module is specially designed for various rf systems. It adopts a dual-channel structure combining power amplifier and low noise amplifier. The transmit channel works at 925-960MHz, with 46±1dBm output power, 52±1dB gain and over 20dB adjustable gain at 1dB step, also equipped with ALC function and EVM ≤8%. The receive channel covers 880-915MHz, featuring 25±1dB gain and noise figure ≤1.8dB. Both channels have in-band fluctuation and VSWR no more than 2.0dB and 1.5 respectively, with excellent spurious suppression. Powered by DC +28V, the integrated power amplifier module is fitted with MCX, SMA ports and RS485 monitoring interface. Operating reliably from -25℃ to +55℃, the B8 40W unit is a reliable core component for professional rf systems.
