Philips Semiconductors
Product specication
Image reject 1800 MHz transceiver
for DECT applications
UAA2067G
Notes
1. Measured and guaranteed only on the Philips demonstration board, including PCB and balun.
2. The imaginary part of the load impedance has been tuned out. A power match is assumed.
3. A simplified DECT type approval measurement is used; the spectrum analyser has the following settings:
RBW = 100 kHz, VBW = 100 Hz, use delta marker and add 50 dB (correction for RBW = 100 kHz), fRFLO = 1.77 GHz
and fIFLO = 120 MHz, f = 4.686 MHz.
