CMD249P5 DC-20 GHz Distributed Power Amplifier Features Functional Block Diagram Ultra wideband performance High linearity High output power Excellent return losses Pb-free RoHs compliant 5x5 QFN package Description The CMD249P5 is wideband GaAs MMIC distributed power amplifier housed in a leadless 5x5 mm plastic surface mount package. The amplifier delivers 12.5 dB of gain with a corresponding output 1 dB compression point of +28 dBm and an output IP3 of 39 dBm at 10 GHz. The CMD249P5 is a 50 ohm matched design which eliminates the need for RF port Note: Vgg2 is optional for gain control matching. o Electrical Performance V = 10.0 V, V = -0.55 V, T = 25 C, F = 10 GHz dd gg A Parameter Min Typ Max Units Frequency Range DC 20 GHz Gain 12.5 dB Noise Figure 3 dB Input Return Loss 15 dB Output Return Loss 15 dB Output P1dB 28 dBm Output IP3 39 dBm Output IP2 38 dBm Supply Current 400 mA ver 1.2 1018 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD249P5 DC-20 GHz Distributed Power Amplifier Specifications Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Drain Voltage, Vdd 10.5 V Vdd 8.0 10.0 10.5 V Idd 350 400 450 mA Gate1 Voltage, Vgg -2.0 to 0 V Vgg1 -0.55 V RF Input Power +30 dBm Channel Temperature, Tch 150 C Electrical performance is measured at specific test conditions.
