... installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the amplifier to a two-pole, three wire grounding mains receptacle. The receptacle must be connected to a fuse or circuit breaker. Connection to any other type of receptacle poses a shock hazard and ...
SHF-0289 SHF-0289Z 0.05 - 6 GHz, 1.0 Watt Product Description
... Passive gate bias circuitry is generally required to achieve pure class AB performance. This is generally accomplished using a voltage divider with temperature compensation. Per item 1 above the gate voltage should be aligned for each device to eliminate the effects of pinchoff process variation. 4. ...
