This document describes the typical curves of the RF/microwave integrated amplifier series, including the gain-frequency curves of three models: HE385C/HEM385C/HES385C. The products have the characteristics of wide frequency range, low noise, high efficiency, good impedance matching, etc., and are suitable for military temperature working conditions.
The HE385C series is an integrated broadband amplifier covering 20‑250 MHz with typical gain of 7‑7.5 dB and low noise figure of 1.8 dB. It delivers about 23 dBm typical output power while maintaining a VSWR of 2.0 : 1 or better.
The device uses an SMA output connector and includes internal filtering and biasing components. Physical dimensions and mounting instructions are provided in the accompanying drawing, and the amplifier can be paired with compatible M/A‑COM AM119 modules. This manual is written in Japanese.
