Default Pete, am looking for a good variable attenuator for UHF

I am building a transmitter combiner for non-conforming wideband FM

dB range and can handle up to 5 Watts input. I have a real clean
final amp http://www.empowerrf.com/docs/1043.doc
but it insists on having a 0 dBm input for full power and minimum
products. Thanks.

I'm leaning toward 2 quad pin diode attenuators in series.


You may want to re-consider that since pin diode attenuators have large
intermodulation products.

Then again you did say it is a non-conforming transmitter.

If you care about intermodulation then go with an electromechanical
type attenuator.
