HE463B/HEM463B wideband amplifier is a microwave thin film circuit with a frequency range of 10 to 2000MHz. It uses an active bias design to provide temperature compensation, has a good 50Ω impedance match, and is easy to cascade.
The HE463B/HEM463B is an integrated broadband RF amplifier covering a frequency range of 10 MHz to 2000 MHz. Typical small‑signal gain is 16 dB (up to 17 dB) with a gain flatness of ±1 dB. Input VSWR is limited to 2.0:1 and output VSWR to 1.7:1, delivering up to 8 dBm output power.
The device operates from a 12 V supply, drawing about 35 mA typical current, and is rated for an ambient temperature range of –55 °C to +85 °C (storage up to +125 °C). It uses SMA connectors and can be used as a replacement for the HP UT0‑2024 model. Mechanical dimensions and mounting instructions are provided in the accompanying drawing.
