3.2.1.3 A3 5W Amplifier Assembly (Schematic 10043496)
The 5W Amplifier Assembly has two gain stages (U1 and Q1) that have a combined gain of approximately
37 dB. The output RF power is greater than 3.5W at the 1 dB compression point
3.3 POWER SUPPLY
Refer to Schematic Diagram 10044273.
PS1 also su15 VDC at 2.5 amps and -15 VDC at 1 amp. PS1 is a switching supply that automatically
sets the AC input circuits to the correct connections for the line voltage 90-264 VAC input ranges 47-440 Hz.
PS1 is a multiple output supply. The main +15V, 10A supplies voltage to the B1 Fan Assembly. The –15 volts
DC is supplied to the A1 module.
PS2 is a single output supply which pr30.0VDC to the RF final stage and to the A1 module
