QBH-175

The QBH-175 is designed as standard hybrid amplifier.

It has four features. The first one is its bandwidth would be from 20 to 500MHz. The next one is that it would have high reverse isolation. The next one is guaranteed specifications over temperature. The next one is it would be unconditionally stable. That are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. The first one is about its power supply voltage which would be +18.0Vdc 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 1.2 Vrms. The next one is about its thermal rise, junction to case which would be +30°C.

Also there are some other specifications about it. The first one is about its frequency range which would be from 20MHz to 500MHz. The next one is about its gain vs. temperature which would be +0.3/-0.5 dB max. The next one si about its gain flatness which would be 0.8dB max p-p. The next one is about its reverse isolation which would be 28dB min. The next one is about its VSWR which would be typ 1.5:1 and max 1.6:1 for input and also for output. The next one is about its 1 dB compression which would be typ +15dBm and min +14dBm. The next one is about its output intercept point which would be typ +29dBm and min +25dBm for 3rd order and would be typ +40dBm and min +33dBm for 2nd order. The next one is about its noise figure which would be typ 3.3dB and max 3.8dB. And so on. For more information please contact us.
