Motorola Hybrid Module Part Number 51-80110E01 I need a pinout and bandwidth data. cannot find any kind of data sheet for this part. Paniks has some parts (way too expensive for me) but no data sheet. I have some parts (scavenged) but no data sheet.
This is the PA module used in Mototola's 15W 800MHz N1353A Mobile STX PA, so I know it's good for 800-900MHz work. What I want to know is the lower end (bandwidth), the required input power for 20W out (which I understand is its true rating) and the pinout/decoupling/bypassing recommendations.
I suppose I can deduce the latter by studying the N1353A innards tediously and the former by sweeping with a network analyzer (which I'm getting in a couple of weeks but I'd like to know now), but I don't know how much power to drive it with, etc.
Possibly there never has been a data sheet on this, may be strictly in-house. Anyone know off hand?[/img]

Oh boy this an old one,
as i remember it is close if not the same as the old MHW820-1 which was a 19 dB gain module, 12.5 to 13.5 volts operation. .25 watts input power for 20 watts max output, operating band rated was 806 to 870 MHz.
They would go up to around 880 to 885,YMMV, before dropping off in Pout and %eff. Below that at around 15% below the lower spec'd frequency you could run into self resonance of the bonding wires on the individual transistors used in the module and they would burn up.
If you want to use one for a 900 ham project forget it they are more pain to make them work than it is worth.
