A 950 MHz subminiature temperature compensated SAW resonator oscillator (TCSO) and a SAW resonator filter are developed in hybrid form for application as local oscillator and bandpass filter f o r a communication system. The oscillator package volume is approximately 0.02 cubic inches and the filter package is approximately 0.01 cubic inches. The extremely tight packaging requirements are met by utilizing chip resistors and capacitors, printed spiral inductors, and chip transistors and diodes. The SAW oscillator consists of a temperature sensing network, a varactor diode tuning circuit, and a single port SAW resonator oscillator. The SAW resonator bandpass filter consists of a four-element input matching network, a two-port two-pole SAW resonator, and four-element output matching network in hybrid form.
