CMD243 26-35 GHz Balanced Driver Amplifier Features Functional Block Diagram Wide bandwidth High gain Low noise and high linearity Excellent return losses Vdd1 2 Small die size Description RFOUT 3 The CMD243 is a wideband GaAs MMIC driver amplifier ideally suited for military, space and communications systems where small size and high linearity are needed. At 30 GHz the device delivers 15.5 dB of gain with a corresponding output 1 dB compression point RFIN 1 of +21 dBm and noise figure of 4.4 dB. The CMD243 is a 50 ohm matched design which eliminates the need for external DC blocks and RF port matching. The CMD243 offers full 4 passivation for increased reliability and Vdd2 moisture protection. o Electrical Performance - V = V = 5.0 V, T = 25 C, F = 30 GHz dd1 dd2 A Parameter Min Typ Max Units Frequency Range 26 - 35 GHz Gain 15.5 dB Noise Figure 4.4 dB Input Return Loss 11 dB Output Return Loss 11 dB Output P1dB 21 dBm Supply Current (I + I ) 90 mA dd1 dd2 ver 1.3 1018 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD243 26-35 GHz Balanced Driver Amplifier Specifications Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Drain Voltage, Vdd1, Vdd2 8 V Vdd1, Vdd2 3.0 5.0 7.0 V Idd1 45 mA RF Input Power +20 dBm Idd2 45 mA Channel Temperature, Tch 150 C Power Dissipation, Pdiss 694 mW Electrical performance is measured at specific test conditions.
