FUNCTIONAL DESCRIPTION
Transmit chain
VCO, BUFFER AND FREQUENCY DOUBLER
The VCO operates at a nominal centre frequency of
950 MHz. It is fully integrated apart from two inductors
which complete the resonator network. This VCO operates
from an on-chip regulated power supply (VREG), which
minimizes frequency disturbances due to variations in
supply voltage. The buffered VCO signal is fed into a
frequency doubler. The large difference between the
transmitted and VCO frequencies reduces
transmitter-oscillator coupling problems.
The output of the doubler is used to drive the synthesizer
main divider and can also be switched to either the TX
preamplifier or the RX LO output buffer. The high isolation
obtained from the VCO buffer and the frequency doubler
ensures very small frequency changes when turning on
the TX preamplifier or the RX LO output buffer. In TX
mode, the oscillator can be directly modulated with GMSK
filtered data at pin VMOD.
RF SWITCH
The RF switch passes the doubled VCO signal to either
the TX preamplifier (when T_EN is HIGH) or to the RX LO
buffer (when T_EN is LOW). In TX mode, the difference in
the RF power levels, observed at the TX output when
T_EN is switched from LOW-to-HIGH, is typically 40 dB.
TX PREAMPLIFIER
The TX preamplifier amplifies the RF signal up to a level of
3 dBm which is suitable for use with Philips
Semiconductors DECT power amplifiers such as the
CGY20xx series. It is powered-up when both R_OFF and
VCO_ON are HIGH.
RX LO BUFFER
The RX LO buffer outputs the frequency doubled VCO
signal at a level of 14 dBm. This signal can then be used
as the local oscillator drive for the receive mixers of
devices such as the UAA2078. The buffer is powered-up
when R_OFF is LOW and VCO_ON is HIGH.
