Frequency Upconverters Span 5.5 To 16.0 GHz

Sept. 15, 2010

A pair of GaAs MMIC frequency upconverters with integral variable-gain amplifiers (VGAs) has been developed by Hittite Microwave Corp. for point-to-point radios, satellite communications, test and measurement systems, and sensor applications from 5.5 to 16.0 GHz. Model HMC924LC5 is an in-phase/quadrature (I/Q) upconverter that operates from 10 to 16 GHz with 15-dB small-signal conversion gain and 30-dB sideband rejection. It has an output third-order intercept point of +14 dBm and LO-to-RF rejection of 15 dB or more. Model HMC925LC5 is an I/Q upconverter for use from 5.5 to 8.6 GHz with small-signal conversion gain of 16.5 dB and 30-dB sideband rejection. It has an output third-order intercept point of +29 dBm and LO-RF rejection of 22 dB or more. Models HMC924LC5 and HMC925LC5 are each housed in a leadless RoHS-compliant QFN 5 x 5 mm QFN surface-mount ceramic package specified for operation from -40 to +85 deg. C.
