CMD241 2-22 GHz Distributed Amplifier Features Functional Block Diagram Vdd Ultra wideband performance 2 Low noise figure Low current consumption Excellent return losses RFOUT Small die size 3 Description RFIN 1 The CMD241 is wideband GaAs MMIC Vgg ACG2 ACG1 distributed low noise amplifier die which 6 5 4 operates from 2 to 22 GHz. The amplifier delivers 14 dB of gain with a corresponding noise figure of 2.3 dB and an output 1 dB compression point of +21 dBm at 11 GHz. The CMD241 is a 50 ohm matched design which eliminates the need for external DC blocks and RF port matching. The CMD241 offers full passivation for increased reliability and moisture protection. o Electrical Performance - V = 5.0 V, V = -0.65 V, T = 25 C, F = 11 GHz dd gg A Parameter Min Typ Max Units Frequency Range 2 - 22 GHz Gain 14 dB Noise Figure 2.3 dB Input Return Loss 20 dB Output Return Loss 17 dB Output P1dB 21 dBm Output IP3 28 dBm Supply Current 74 mA ver 1.5 1018 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD241 2-22 GHz Distributed Amplifier Specifications Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Drain Voltage, Vdd 10 V Vdd 5.0 5.0 8.0 V Idd 74 mA Gate Voltage, Vgg -2.5 to 0 V Vgg -0.65 V RF Input Power +20 dBm Channel Temperature, Tch 150 C Electrical performance is measured at specific test conditions.
