Estimating the term…
A complimentary switched amplifier transceiver (10) is provided which offers performance advantages and reduces system complexity over conventional half-duplex transceivers by using complimentary switched amplifiers for eliminating switches. Power output to a channel transition (31) from a transmit amplifier (26) is not degraded by a switch insertion loss in a transmit mode. Receiver noise figure is not degraded due to the switch insertion loss from the channel transition (31) to a receive amplifier (27). Switch devices and their associated control lines are eliminated, reducing circuit complexity for complimentary switched amplifier circuits such as a combined amplifier switch (12) and a first bi-directional amplifier (22).
A complimentary switched amplifier transceiver, comprising:
A method achieving half-duplex transceiver operation in a system having a channel transition comprising the steps of:
A method of providing a complimentary switched amplifier comprising the steps of:
An amplifier comprising:
