Abstract:

The investigation of S-band solid-state receiver components has begun with the evaluation of a tunable YIG preselector, a transitorized balanced mixer, and a broad-band IF amplifier. The miniature yttium-iron-garnet two-resonator filter can be tuned over more than one octave by varying the magnet curent with a single voltage control. A balanced mixer was constructed using a transmission-line transformer and the base-toemiter diode of a germanim transistor. However, at frequencies above half of the unity current gain frequency of the transistor, the local-oscillator power required increased, and the noise figure began to deteriorate. Broadband IF amplifiers were constructed and tested. These transistorized, two-stage amplifiers had a high-frequency response of 475 mc with a 300-mc bandwidth and a gain of 10 db. Author
