Electrical Characteristics

(at 25°C) Ω system, Vd = +7V, quiescent current (Idq) = 300 mA, GC1, GC2 = +1.5V Notes: 1. Typical range of the negative gate voltage is -0.9 to 0.0V to set typical Idq of 300 mA. 2. GC1 and GC2 of +1.5V and VG23 = open corresponds to maximum gain and power. Figure 1. Block Diagram and Circuit Schematic Figure 2. Location and Size of Bonding Pads (Dimensions in Inches)

C RMM2080 Performance Data The above data is derived from fixtured measurements which include 3 parallel, 1 mil diameter, 15 mil long, gold bond wires connected to the RF input and output. The Id @ 1dB compression increases to approximately 0.45 A. The dc supply should be able to support the required current to achieve the above performance. 0.00 5.00 10.00 15.00 20.00 25.00 30.00 35.00 Vcontrol (V) 2GHz 10GHz 18GHz Gain Return Loss (dB) Gain (dB) Gain (dB) P1 (dBm) Frequency (GHz) Input & Output Return Loss Vd=7.0V, Id=0.3A, GC1,2=1.5V Small Signal Gain Vd=7.0V, Id=0.3A, GC1,2=1.5V Gain & Pout vs, Control Voltage Vd=7.0V, Id=0.3A @ GC1,2=1.5V 02468 1 2 10 14 16 18 20 Frequency (GHz) 02468 1 2 10 14 16 18 20 S22 S11
