CMD178C3 CCMMDD117788CC33 11-21 GHz Fundamental Mixer Features Functional Block Diagram Low conversion loss High isolation Wide IF bandwidth Passive double balanced topology Pb-free RoHs compliant 3x3 mm SMT package Description The CMD178C3 is a general purpose double balanced mixer in a leadless surface mount package that can be used for up- and downconverting applications between 11 and 20 GHz. The CMD178C3 has very high isolation to both the RF and IF ports due to the optimized balun structures, and can operate with an LO drive level as low as +9 dBm. The CMD178C3 can easily be configured as an image reject mixer or single sideband modulator with external hybrids and power splitters. o Electrical Performance - IF = 100 MHz, LO = +13 dBm , T = 25 C, F = 15 GHz A Parameter Min Typ Max Units Frequency Range, RF & LO 11 - 21 GHz Frequency Range, IF DC 6 GHz Conversion Loss 6 dB LO to RF Isolation 45 dB LO to IF Isolation 45 dB RF to IF Isolation 26 dB Input P1dB 9 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.5 1017 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD178C3 CCMMDD117788CC33 11-21 GHz Fundamental Mixer Specifications Absolute Maximum Ratings Parameter Rating RF / IF Input Power +25 dBm LO Drive +25 dBm Operating Temperature -40 to 85 C Storage Temperature -55 to 150 C Operation of this device outside the maximum ratings may cause permanent damage. o Electrical Specifications - IF = 100 MHz, LO = +13 dBm, T = 25 C A Parameter Min Typ Max Min Typ Max Units Frequency Range, RF & LO 13 - 17 11 - 21 GHz Frequency Range, IF DC 6 DC 6 GHz Conversion Loss 6 8 7 10 dB Noise Figure (SSB) 6 8 7 10 dB LO to RF Isolation 35 43 31 43 dB LO to IF Isolation 33 48 30 38 dB RF to IF Isolation 17 25 15 25 dB Input P1dB 9 9 dBm Input IP3 16 16 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.5 1017 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com
