Subject: [Repeater-Builder] M57719N RF power module
Anybody have any suggestions on varing the power on the M57719N Power
Module?
Would it be best to limit the rf input?
Would it be ok to lower the vcc on the module?
which would be the best approach?

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
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.Tony Faiola [EMAIL PROTECTED] wrote:

---According to the datasheet
Brent,
Typical RF power amplifier modules are most efficient and produce the
least spurious output when operated at the rated output level. The
M57719N is rated at 14 watts on a 12.5 VDC supply, over the 142-163 MHz
range. When you start reducing the drive or lowering the supply voltage,
