UAA2067G

FUNCTIONAL DESCRIPTION

Receive section

Transmit section

The circuit contains two balanced mixers, each of which is

driven by the RFLO and IFLO signals. The output signal of

the two mixers is summed and buffered to obtain the single

upper-sideband signal at frequency RFLO + IFLO.

The circuit contains a balanced low-noise amplifier

followed by two high dynamic range mixers. The local

oscillator signals, shifted in phase to 0 and 90° mix the

amplified RF signal to the I and Q channels.These two

channels are buffered, phase shifted by 45° and 135°

respectively, amplified and recombined internally to realize

the image rejection. Signals at the RF input at RFLO − IF

frequencies are rejected through the signal processing

while signals at the RFLO + IF frequencies form the

IF signals.

With the use of an off-chip time constant, the ramping

circuit defines the power ramp-up and ramp-down of the

pre-amplifier output signal.

Balanced signals are used for minimizing crosstalk due to

package parasitics.

Fast switching, on/off, of the transmit section is controlled

by the hardware input PDTX.

An image rejection of typically 34 dB is obtained for an IF

between 100 and 120 MHz.

The power supply voltage of the transmit mixers, the

adding circuit and ramping circuit is taken from the

Balanced signals are used for minimizing crosstalk due to

package parasitics. The IF output is single-ended.

The typical load is 50 Ω.

_CC(MIX)and GND6 for maximum isolation from the

preamplifier output stage.

Fast switching, on/off of the receive section is controlled

by the hardware input PDRX.

OPERATING MODES

To use the IC, all V_CCpins must be connected to the

supply voltage.

RFLO section

For transceiving a DECT signal, the RFLO and IFLO

sections should be powered-on. After a stable frequency

has been reached (mainly determined by the synthesizer

design), the receiver or transmitter can be powered-on.

The high-frequency oscillator (RFLO oscillator) supplies

the local oscillator signal for the down-conversion (receive)

and up-conversion (transmit) mixers. This VCO uses an

on-chip regulator for a power-supply voltage-independent

output frequency. The buffered VCO signal is fed into a

phase shifter and an off-chip prescaler-synthesizer.

The output signal of the phase-shifter is used for driving

the RX and TX mixers. Due to the good isolation in the

buffer stages, a very small change in VCO frequency is

obtained when switching the RX and TX mixers on.

GMSK data modulation can be supplied in two different

ways: the data is directly modulated on IFLO or RFLO.

The ramping of the power level can be set with a time

constant that is external to the IC.

Table 1 gives the definition of the polarity of the switching

signals on the receive, the RFLO, the IFLO and the

transmit sections.

Fast switching, on/off of the oscillator section is controlled

by the hardware input PDRFLO.

IFLO section

The low-frequency oscillator (IFLO oscillator) internally

supplies the local oscillator signal to the single-sideband

transmit mixer. The buffered VCO signal is fed into a

phase shifter. The output signal of the phase-shifter is

used for driving the TX mixers.

Due to the good isolation in the buffer stages, a very small

change in VCO frequency is obtained when switching the

TX mixer on.

Fast switching on/off of the oscillator section is controlled

by the hardware input PDIFLO input.
