Abstract :
An innovative monolithic single sideband modulator (SSBM) which utilizes balanced subharmonically pumped mixers has been developed. This SSBM is pumped at one-half of the carrier frequency. The typical measured performance of this device is excellent, with greater than 40 dB carrier suppression, greater than 25 dB undesired carrier suppression, and less than 10 dB conversion loss over a carrier bandwidth of 14 to 19 GHz. Double sideband suppressed carried and unsuppressed carrier operation is also achievable with the same device when appropriate modulation signals are applied.<>
