CMD251 C3 4-8.5 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 CMD251C3 is a general purpose double balanced mixer in a leadless surface mount package that can be used for up- and downconverting applications between 4 and 8.5 GHz. The CMD251C3 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 +15 dBm. The CMD251C3 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 = +17 dBm , T = 25 C, F = 6 GHz A Parameter Min Typ Max Units Frequency Range, RF & LO 4 8.5 GHz Frequency Range, IF DC 2.2 GHz Conversion Loss 7 dB LO to RF Isolation 45 dB LO to IF Isolation 36 dB RF to IF Isolation 25 dB Input IP3 21 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.0 0717 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD251 C3 4-8.5 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 280.4 C/ W Thermal resistance, JC Operation of this device outside the maximum ratings may cause permanent damage. o Electrical Specifications IF = 100 MHz, LO = +17 dBm, T = 25 C A Parameter Min Typ Max Min Typ Max Units Frequency Range, RF & LO 4 7 7 8.5 GHz Frequency Range, IF DC 2.2 DC 2.2 GHz Conversion Loss 7 8.5 8.5 10 dB Noise Figure (SSB) 7 8.5 8.5 10 dB LO to RF Isolation 40 45 40 45 dB LO to IF Isolation 30 40 42 50 dB RF to IF Isolation 15 25 30 35 dB Input P1dB 16 17 dBm Input IP3 22 25 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.0 0717 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com
