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 (82nH) 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 247 mils from the edge of AH322 RFout pin (11 º @ 1960 MHz).
6. Do not exceed +5.5V supply or TVS diode D3 will be damaged.
7. 0 jumpers may be replaced with copper traces in the target application layout.
8. DNP implies Do Not Place.
