between the power amplifier and the antenna is redundant and may consequently be removed. Image rejection is achieved in the internal
architecture by two RF mixers in quadrature and two phase shifters in the low-frequency VCO signal that shifts the phase to 0° and 90°.
The output signals of the mixers are summed to form the single-upper-sideband output signal.
The output stage is a high-level output buffer with an output power of approximately 4 dBm. The output level is sufficient to drive a three-
stage bipolar preamplifier for DECT.
