The design of a differential distributed amplifier using close-packed transmission lines is discussed along with the implementation of a differential distributed oscillator. Efficient layout techniques for the implementation of these circuits are demonstrated. A differential distributed amplifier with 25 GHz of bandwidth and 7.5 dB of gain is presented as a design example. The amplifier can also be configured as a 9.2 GHz distributed oscillator with -6 dBm single-ended output power, phase noise of -103 dBc/Hz at a 1 MHz offset, and a 17% tuning range.
