CMD258 7.5-13 GHz High IP3 I/Q Mixer Features Functional Block Diagram Low conversion loss High IP3 Image rejection: 29 dB LO Wide IF bandwidth 2 -90 Small die size RF 1 Description 0 The CMD258 is a high IP3 I/Q mixer die that can be used as either an image reject mixer or a single sideband upconverter. The CMD258 IF1 IF2 utilizes two double balanced mixer cells and a 4 3 90 degree hybrid. An external IF hybrid is needed to complete the image rejection. The CMD258 offers full passivation for increased reliability and moisture protection. o Electrical Performance - IF = 100 MHz, LO = +21 dBm , T = 25 C, F = 10 GHz A Parameter Min Typ Max Units Frequency Range, RF & LO 7.5 - 13 GHz Frequency Range, IF DC 3.5 GHz Conversion Loss (as IRM) 5.5 dB Image Rejection 29 dB LO to RF Isolation 38 dB LO to IF Isolation 20 dB Input P1dB 14.5 dBm Input IP3 25 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.1 0719 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com CMD258 7.5-13 GHz High IP3 I/Q Mixer Specifications Absolute Maximum Ratings Parameter Rating RF / IF Input Power +27 dBm LO Drive +27 dBm Operating Temperature -55 to 85 C Storage Temperature -55 to 150 C Thermal Resistance, 135.5 C/W JC Power Dissipation, Pdiss 477 mW Exceeding any one or combination of the maximum ratings may cause permanent damage to the device. o Electrical Specifications - IF = 100 MHz, LO = +21 dBm, T = 25 C A Parameter Min Typ Max Min Typ Max Units Frequency Range, RF & LO 9 - 11 7.5 - 13 GHz Frequency Range, IF DC 3.5 DC 3.5 GHz Conversion Loss (as IRM) 5.5 7.5 7 10 dB Image Rejection 23 28 23 30 dB LO to RF Isolation 34 38 34 42 dB LO to IF Isolation 15 19 14 20 dB Input P1dB 15 16 dBm Input IP3 24 24 dBm Unless otherwise noted, all measurements performed as a downconverter, IF = 100 MHz ver 1.1 0719 Custom MMIC 300 Apollo Drive Chelmsford, MA 01824 Phone (978) 467-4290 Fax (978) 467-4294 Visit us online at www.custommmic.com
