Abstract:
1. An analog cordless telephone having a handset and a base, said telephone comprising: in at least one of the handset and the base, 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 adapted to gate a received audio signal on and off, in response to a clock signal; and a second analog gate adapted to gate a transmit audio signal on and off, in response to an inverted version of the clock signal; wherein 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 wherein a frequency of the clock signal for the handset is different than a frequency of the clock signal for the base.
