A bit of advice:

The Motorola data book suggests that these devices are designed for Class C
service, and their design guide gives a circuit without DC bias. The Vbe max
is only 4 Volts, which gives a useful hint!

Your DC bias circuit needs to /very/ accurately track temperature to prevent
thermal runaway - the design of the bias circuit /will/ /not/ be trivial.

The gain of the circuit will be disappointing - you'll be lucky to get close
to 10 dB - so the drive requirement will be surprisingly high.

If I was designing a UHF PA, I'd choose FETs these days!
