Notes:
1. ACLR test set-up: 3GPP WCDMA, TM1±64 DPCH, ±5MHz offset no clipping, PAR = 10.34 dB @
0.01% Probability.
2. OIP3 is measured at 24 dBm / tone output power with 1 MHz spacing.
3. The multilayer inductor L3 (82 nH) is critical for linearity performance..
4. Vpd is used as device power down voltage (low = RF off).
5. The edge of C5 is placed at 195 mils from the edge of AH322 RFout pin (22 º @ 2140 MHz).
6. The edge of C8 is placed at 0.5 mils from the edge of AH322 RFout pin (0 º @ 2140 MHz).
7. Zero ohm jumpers may be replaced with copper traces in the target application layout.
8. DNP means Do Not Place.
