HE394B/HEM394B integrated broadband amplifier, with a frequency range of 10 to 1000MHz, uses active bias design to provide temperature compensation, good 50Ω impedance matching, easy cascading, microwave thin film circuit structure, stable electrical performance, standard full sealing tube shell packaging, meets military temperature working conditions: -55℃ to +85℃.
The HE394B/HEM394B is an integrated broadband RF amplifier designed for operation from 10 MHz to 1000 MHz. Typical small‑signal gain is 15 dB (up to 16 dB) with a gain flatness of 0.5 dB, and both input and output VSWR are kept below 2.0:1.
The device operates from –55 °C to +85 °C, can be stored up to +125 °C, and requires a +6 V supply. Maximum input power is +10 dBm, while typical output power is 15 dBm. It is housed in a TO‑8C/SMO‑8C package and includes external connections for four‑port integration. This manual is written in Chinese.
