A 75–110GHz (W band) high-Q tunable band pass filter is demonstrated. The band pass filter has low insertion loss, a Q of approximately 200 and can be tuned across the entire W waveguide band. This filter has a variety of uses including rejecting spurious signals generated from non-linear frequency multiplication and improving signal to noise ratio at the front end of a receiver. The tuning is achieved...
A voltage controlled oscillator (VCO) was designed for operation in C-band for use in a microwave point-to-point radio system. Microstrip technology was chosen for resonator implementation since it offers ease of manufacturing and frequency adjustment The design was performed using an electromagnetic (EM)-harmonic balance co-design technique in order to achieve first pass success. The measured frequency...
