TYPICAL APPLICATION DIAGRAM (TARGETING IEEE 802.11 STANDARD)
NOTES:
1. Input termination used to match a SAW filter.
2. Typical bandpass filter for 280MHz, BW = 47MHz, Q = 6. Can also be used if desired after the second stage.
3. Network shown for a typical -10dBm input at 50Ω.
4. Output termination used to match a SAW filter.
5. RTUNE value for a 7.7MHz cutoff frequency setting.
6. LO buffer output termination is needed only when the buffer is enabled by pin 50 connected to GND, otherwise tie pin 46 to pin 47.
