Notes:
1. ACPR test set-up: IS-95 CDMA, 9 channels fwd, ±885 KHz offset, 30 KHz, Meas BW, PAR = 9.7 dB
@ 0.01% Prob.
2. ACLR test set-up: 3GPP WCDMA, TM1±64 DPCH, ±5MHz offset no clipping, PAR = 10.34 dB @
0.01% Probability.
3. OIP3 is measured at 21 dBm / tone output power with 1 MHz spacing.
4. Vpd is used as device power down voltage (low = RF off).
5. The edge of L2 is placed at 380 mils from the edge of AH322 RFout pin (19 º @ 940 MHz)
6. The edge of C2 is placed at 190 mils from the edge of AH322 RFout pin (9.5 º @ 940 MHz).
7. Do not exceed +5.5V supply or TVS diode D3 will be damaged.
8. 0 jumpers may be replaced with copper traces in the target application layout.
9. DNP implies Do Not Place.
