THE DEVELOPMENT OF A LOW-NOISE L-BAND CYCLOTRON-WAVE LINEATOR
Abstract
The object of the project was to design, develop, and con struct a feasibility model of a low-noise L-band cyclotron-wave device (LINEATOR) for isolation and overload protection of a solid-state negative resistance preamplifier for high-power radar. The operating frequency is centered at 1,295 Mc. A feasibility model complete with solenoid and power supplies, and packaged in a form suitable for complete performance testing on a general-purpose space- tracking and measurements radar constructed by Lincoln Laboratories was delivered. This unit has the capability of withstanding 50 kw of peak incident power and providing greater than 100 db of isolation to the solid-state amplifier during the transmitter pulse. Recovery is automatic and essentially instantaneous. During the receiving period the terminal insertion loss is approximately 0.3 db, with a total effective input noise temperature less that 35K.
