HE390B integrated broadband amplifier performance table, including frequency range, gain, noise figure, input return loss, output return loss, linear output power, working current, appearance size, installation and use methods
The document details the performance characteristics of the HE390B broadband amplifier, including its typical frequency range of 20‑520 MHz, gain of 15‑16.5 dB, and a typical output power of 43 dBm. It also lists VSWR values (≈2.0:1 input, 1.7:1 output) and operating temperature limits up to +125 °C.
Installation notes cover the required +12 V supply, connector options such as SMA‑3 and SMA‑female, and mechanical dimensions. Users are advised on power handling limits, recommended bias voltages, and wiring guidelines for optimal operation. This manual is written in Japanese.
| Gain | 15.0‑16.5 dB |
|---|---|
| Output power (TP3 out) | 43 dBm (typical) |
| Maximum input level | +17 dBm |
| Maximum operating temperature | +125 °C |
Its typical small‑signal gain is between 15.0 dB and 16.5 dB.
The TP3 output delivers about 43 dBm under typical conditions.
