If you are going to use the PA module at reduced(adjustable) power I would reccomend a linear unit as opposed to a Class C unit. It is designed for a full range of drive without restrictions, (within reason). Less concerns about spurious. Just a thought.

Hello Brent:
I have been working with some of these bricks from Toshiba and
Mitsubishi. If you ordered the module or are ordering this module from
RF Products, buy the specifications sheet ($1.50) with the module.
The specification sheet has much valuable data in it including a power
input verses power output curve, etc.
It's usually easier to lower an input stage than the power module (drive
level) using lower voltage or low power pad techniques.
Looking at the aforementioned spec sheet curves, they show you what
power output you can expect verses power input.
You do need to be careful of the power module output spectral quality
with these procedures.
Hope these few tips help.
Ciao, Tony K3WX
