CMD179C3 CCMMDD117799CC33 16-26 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 CMD179C3 is a general purpose double balanced mixer in a leadless surface mount package that can be used for up- and downconverting applications between 16 and 26 GHz. The CMD179C3 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 CMD179C3 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 = 21 GHz A Parameter Min Typ Max Units Frequency Range, RF & LO 16 - 26 GHz Frequency Range, IF DC 9 GHz Conversion Loss 6.5 dB LO to RF Isolation 40 dB LO to IF Isolation 48 dB RF to IF Isolation 26 dB Input P1dB 10 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.6 1017 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD179C3 CCMMDD117799CC33 16-26 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 18 - 24 16 - 26 GHz Frequency Range, IF DC 9 DC 9 GHz Conversion Loss 6.5 8 7 10 dB Noise Figure (SSB) 6.5 8 7 10 dB LO to RF Isolation 37 43 36 43 dB LO to IF Isolation 38 48 29 43 dB RF to IF Isolation 18 25 15 25 dB Input P1dB 10 10 dBm Input IP3 17 17 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.6 1017 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com
