... DC ground and requires both of the device grounds (Pins 1 and bypassed. Device current, Id, is determined by the value of the source resistance, Rbias, between either Pin 1 or Pin 4 of the MGA-72543 and DC ground. Note: Pins 1 and 4 are connected internally in the RFIC. Maximum device current (approximately 65 mA) occurs for Rbias = 0 ...

... A DC blocking capacitor at the output of the RFIC isolates the supply voltage from succeeding circuits. If the source resistor method of biasing is used, the RF input terminal of the MGA-72543 ground potential and a blocking capacitor is not required unless the input is connected di- rectly to a preceding stage that has a DC voltage present. ...

... The state of the MGA-72543 (amplifier or bypass mode) is controlled by the device current. For device currents greater than 5 mA, the MGA-72543 functions as an am- plifier. If the device current is set to zero, the MGA- 72543 is switched into a bypass mode in which the amplifier is turned off and the signal is routed around the amplifier with a loss of approximately 2 ...

... Figure 12. This evalua- tion circuit is designed for operation from a +3-volt supply and includes provision for a 2-bit DIP switch to set the state of the MGA-72543. For evaluation purposes, the 2-bit switch is used to set the device to either of four states: (1)bypass mode – switch bypasses the amplifier, (2)low noise amplifier mode – ...
