S-AV7

The S-AV7 is a kind of RF power amplifier module. S-AV7 is intended for VHF marine FM RF power amplifier module. It features high gain (PO28 W, GP21.4 dB, T45%).

Then is about S-AV7 maximum ratings (Tc=25): (1)DC supply voltage, VCC: 16 V; (2)DC supply voltage, VCON: 16 V; (3)input power, Pi: 300 mW; (4)operating case temperature range, Tc(opr): -30 to 100; (5)storage temperature range, Tstg: -40 to 110.

The following is about S-AV7 electrical characteristics (Tc=25): (1)frequency range, frange: 144 MHz min and 148 MHz max; (2)output power, PO: 28 W min and 33 W max at Pi=200 mW, VCC=12.5 V, VCON=12.5 V, ZG=ZL=50; (3)total efficiency, T: 45% min and 52% typ at Pi=200 mW, VCC=12.5 V, VCON=12.5 V, ZG=ZL=50; (4)input VSWR, VSWRin: 1.5 typ and 2 max at Pi=200 mW, VCC=12.5 V, VCON=12.5 V, ZG=ZL=50; (5)harmonics, HRM: -30 dB typ and -25 dB max at Pi=200 mW, VCC=12.5 V, VCON=12.5 V, ZG=ZL=50; (6)load mismatch: no degradation when VCC=15 V, VCON=12.5 V, PO=30 W (Pi=adjust), VSWR load 20:1 all phase; (7)stability: all spurious output than 60 dB below desired signal when VCC=12.5 V,  VCON=0 to 12.5 V, Pi=200 mW, VSWR load 3:1 all phase; (7)power slump: 0.8 dB typ at Tc=-30 to 80, VCC=12.5 V, Pi=200 mW, PO=28 W (@ TC=25); (8)power gain, GP: 21.4 dB min and 22.2 dB max at Pi=200 mW, VCC=12.5 V, VCON=12.5 V, ZG=ZL=50.
