Abstract
An analog cordless telephone has a handset and a base. The handset and/or the base of the telephone may include the following components. A phase locked loop (PLL) and a voltage controlled oscillator (VCO), adapted to be shared between a receive path and a transmit path. A first analog gate is adapted to gate a received audio signal on and off, in response to a clock signal. A second analog gate is adapted to gate a transmit audio signal on and off, in response to an inverted version of the clock signal. The transmit audio signal is enabled when the received audio signal is gated off, and the VCO is further adapted to be modulated by the enabled transmit audio signal to output a modulated RF signal.
