QBH-145

The QBH-145 is designed as standard hybrid amplifier.

QBH-145 has four features. The first one is it would have 10 to 150MHz bandwidth. The next one is it would have high reverse isolation. The next one is it would have very flat gain response. The next one is it would have guaranteed stability. That are all the main features.

Some absolute maximum ratings of QBH-145 have been concluded into several points as follow. The first one is about its power supply voltage which would be +20.0Vdc for sustaining and would be +25.0Vdc for pulse (transient). The next one is about its operating temperature range which would be from -55°C to +125°C. The next one is about its storage temperature range which would be from -65°C to +150°C. The next one is about its maximum input drive which would be 2.0 Vrms. The next one is abut its thermal rise, junction to case which would be +31°C.

Also there are some other specifications about QBH-145. The first one is about its temperature which would be typ +25°C and should be within from -55°C to +85°C. The next one is about its frequency range which would be from 10 to 150MHz. The next one is about its small signal gain which would be 13.0 ± 0.5dB. The next one is about its gain vs. temperature which would be max +0.4/-1.0 dB. The next one is about its gain flatness which would be typ 0.4dB and max 0.5dB. The next one is about its reverse isolation which would be typ 31dB and min 30dB. The next one is about its VSWR which would be max 1.5:1 for input and also for output. The next one is about its 1 dB compression which would be typ +19dBm and min +16dBm. The next one is about its noise figure which would be typ 5.8dB and max 6.5dB. And so on.
