This pad is DC coupled and matched to 50Ω from DC to 20GHz. 50Ω microstrip transmission line on 0.127mm (5mil) thick alumina thin film substrate is recommended for RF input and output. 2 VG2 VG2 is an optional pad. It may be used to bias the cascode gate of the amplifier. If this port is used, a 1000pF bypass capacitor with the shortest wirebond length possible is recommended to prevent low frequency gain ripple. 3 VTO The output drain termination pad. This pad requires a suggested 1000pF bypass capacitor with the shortest wirebond length to prevent low frequency gain ripple. The value of the external capacitance limits the low frequency response of the amplifier. 4 RFOUT and VDD 5 VCAS Provides VG2 gate voltage to the cascode amplifier. The value is ~ (VCC/2 – absolute value of VTI). 6 VG21 Not connected. Interface Schematic RF Output. 50Ω microstrip transmission line on 0.127mm (5mil) thick alumina thin film substrate is recommended for RF input and output. Connect the DC bias (VDD) network to provide drain current (IDD). 7 VTI Input gate voltage, used to bias the amplifier. The value is between -1.5VDC (device is pinched OFF) to +0.2VDC (fully ON). This pad requires a bypass capacitor to ground with the shortest possible wirebond length to prevent low frequency gain ripple. The value of the external capacitance limits the low frequency response of the amplifier. Die GND Ground connection. Connect die bottom directly to ground plane for best performance. NOTE: The die should be connected directly to the ground plane with conductive epoxy.

Data was taken using a temperature controlled probe station utilizing 150μm pitch GSG probes. The interface between the probes and integrated circuit was made with a coplanar to microstrip ceramic test interface. The test interface was then wire bonded to the die as shown in the figure below using 1mil diameter bondwires. The spacing between the test interface and the die was 200μm, and the bond wire loop height was 100μm. The thickness of the test interface is 125μm (5mil). The calibration of the test fixture included the probes and test interfaces, so that the measurement reference plane was at the point of bond wire attachment. Therefore, all data represents the integrated circuit and accompanying bond wires.
