A Ku‐band push‐push VCO for low‐cost applications is proposed. The proposed push‐push oscillator achieves a wide tuning range in the Ku‐band by the collector bias tuning instead of varactor tuning. The designed Ku‐band VCO shows a wide tuning range of 900 MHz, excellent fundamental suppression of −30 dBc, and good phase noise of −115 dBc at 1‐MHz offset. © 2006 Wiley Periodicals, Inc.
