CMD249 DC-20 GHz Distributed Power Amplifier Features Functional Block Diagram Ultra wideband performance 2 3 ACG1 ACG2 High linearity High output power Excellent return losses RFOUT & Vdd 4 Small die size Description RFIN 1 Vgg ACG3 GB ACG4 The CMD249 is wideband GaAs MMIC dis- 8 7 6 5 tributed power amplifier die which operates from DC to 20 GHz. The amplifier delivers greater than 12 dB of gain with a correspond- ing output 1 dB compression point of +30 dBm and output IP3 of 38 dBm at 10 GHz. The CMD249 is a 50 ohm matched design which eliminates the need for RF port matching. The CMD249 offers full passivation for increased reliability and moisture protection. o Electrical Performance V = 10.0 V, V = -0.95 V, T = 25 C, F = 10 GHz dd gg A Parameter Min Typ Max Units Frequency Range DC 20 GHz Gain 13 dB Noise Figure 3.4 dB Input Return Loss 16 dB Output Return Loss 17 dB Output P1dB 30 dBm Supply Current 400 mA ver 1.5 1018 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD249 DC-20 GHz Distributed Power Amplifier Specifications Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Vdd 8.0 10.0 10.5 V Drain Voltage, Vdd 10.5 V Idd 350 400 450 mA Gate1 Voltage, Vgg -2.0 to 0 V Vgg -0.95 V RF Input Power +30 dBm Igg -2.5 mA Channel Temperature, Tch 150 C Power Dissipation, Pdiss 4 W Electrical performance is measured at specific test conditions.
