System and method of transistor switch biasing in a high power semiconductor switch
First Claim
Patent Images
1. A high power switch comprising:
- a first transistor group switch including a plurality of first transistors of a first type, the first transistor group switch coupled along a signal path formed between a first end and a second end; and
a second transistor group switch including a plurality of second transistors of a second type, the second transistor group switch coupled along a shunt path formed between a shunt end and at least one of the first and second ends of the signal path, a drain and a source of at least one of the first transistors being held at a substantially similar biasing voltage as that applied to a drain and a source of at least one of the second transistors when the switch is in a series mode and when the switch is in a shunt mode.

Abstract
A circuit and method are provided for switching in a semiconductor based high power switch. Complementary p-type based transistors are utilized along insertion loss insensitive paths allowing biasing voltages to alternate between supply and ground, allowing for negative voltage supplies and blocking capacitors to be dispensed with, while improving performance.
