QBH-142

The QBH-142 is designed as standard hybrid amplifier.

QBH-142 has five features. The first one is it would have 10 to 140MHz bandwidth. The next one is it would have low noise figure. The next one is it would have low power operation. The next one is it would have guaranteed specifications over temperature. The next one is it would have very flat gain response. That are all the main features.

Some absolute maximum ratings of QBH-142 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 1.0 Vrms. The next one is abut its thermal rise, junction to case which would be +14°C.

Also there are some other specifications about QBH-142. 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 140MHz. The next one is about its small signal gain which would be 15.3 ± 0.5dB. The next one is about its gain vs. temperature which would be max +0.5/-0.7 dB. The next one is about its gain flatness which would be typ 0.3dB and max 0.6dB. The next one is about its reverse isolation which would be typ 34dB and min 34dB. 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 +7dBm and min +6dBm. The next one is about its noise figure which would be typ 2.3dB and max 3.0dB. And so on.
