This document introduces the RF/microwave integrated amplifier series in the Shijiazhuang City 179 Mailbox 76 Mailbox. The series includes HE321D/HEM321D/HES321D integrated broadband amplifiers, which have the characteristics of wide frequency range, flat gain, good impedance matching, and stable and reliable electrical performance.
This manual provides the performance specifications of the HBM integration broadband amplifier, including a frequency range of 10‑1000 MHz, typical small‑signal gain of about 18 dB, and input/output VSWR values of 2.0:1. Typical gain curves and other electrical parameters are listed in the specification tables.
Installation instructions describe the recommended power supply (12 V), recommended component values for input matching (C=3.3‑22 nF, C=3300‑6800 pF, C=1000 pF), and mechanical dimensions. The document also references a separate drawing for package dimensions and mounting details. This manual is written in Chinese.
