CMD246 CCMMDD224466 8-22 GHz Low Phase Noise Amplifier Features Functional Block Diagram Wide bandwidth Vdd 2 Low phase noise Low current consumption Small die size RFOUT 3 Description RFIN 1 The CMD246 is a wideband GaAs MMIC low phase noise amplifier ideally suited for mili- 4 Vgg tary, space and communications systems. At 16 GHz the device delivers 17 dB of gain, a saturated output power of +18 dBm and a noise figure of 3.5 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 CMD246 is a 50 ohm matched design which eliminates the need for RF port match- ing. The CMD246 offers full passivation for increased reliability and moisture protection. o Electrical Performance - V = 5.0 V, V = 3.0V, T = 25 C, F=16 GHz dd gg A Parameter Min Typ Max Units Frequency Range 8 - 25 GHz Gain 17 dB Input Return Loss 8 dB Output Return Loss 13 dB Noise Figure 3.5 dB Output P1dB 13 dBm Saturated Output Power 18 dBm Phase Noise 10 kHz Offset -165 dBc/Hz Supply Current 48 mA ver 1.1 1116 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD246 CCMMDD224466 8-22 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 48 mA Gate Voltage, Vgg 5.0 V Vgg 0 3.0 4.0 V RF Input Power +15 dBm Channel Temperature, Tch 150 C Electrical performance is measured at specific test conditions.
