CMD245C4 6-18 GHz Low Phase Noise Amplifier Features Functional Block Diagram Wide bandwidth Low phase noise Low current consumption Pb-free RoHs compliant 4x4 mm SMT package Description The CMD245C4 is a wideband GaAs MMIC low phase noise amplifier housed in a leadless surface mount package that is ideally suited for military, space and communications systems. At 10 GHz the device delivers 18 dB of gain, a saturated output power of +21 dBm and a noise figure of 4.5 dB. Also with an input signal of 10 GHz the amplifier provides low phase noise performance of -165 dBc/Hz at 10 kHz offset. The CMD245C4 is a 50 ohm matched design which eliminates the need for RF port match- ing. o Electrical Performance V = 5.0 V, V = 3.0 V, T = 25 C, F = 10 GHz dd gg A Parameter Min Typ Max Units Frequency Range 5 20 GHz Gain 18 dB Input Return Loss 10 dB Output Return Loss 12 dB Noise Figure 4.5 dB Output P1dB 18 dBm Saturated Output Power 21 dBm Phase Noise 10 kHz Offset -165 dBc/Hz Supply Current 76 mA ver 1.2 1017 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD245C4 6-18 GHz Low Phase Noise Amplifier Specifications Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Drain Voltage, Vdd 8.0 V Vdd 3.0 5.0 7.0 V Idd 76 mA Gate Voltage, Vgg 5.0 V Vgg 0 3.0 4.0 V RF Input Power +17 dBm Channel Temperature, Tch 150 C Electrical performance is measured at specific test conditions.
