Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 7
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over temp
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
4. Typical values are based on average measurements at room temperature
5. Over a sliding 5 MHz window, in-band
6. Relative to zero dB
7. All power levels are referenced to the antenna port. Two CW tones are applied at frequencies f1 and f2, and the resultant
intermodulation product in the Rx band is measured. The first tone is applied to the Tx port, in the range f1 = 777 to 787 MHz, at
+21.5 dBm (referenced to the antenna port). The second tone is -15 dBm, applied to the antenna port at f2, with the following four
cases:
a. f2 = 31 MHz
b. f2 = 2 * f1 - 31 MHz
c. f2 = f1 + 31 MHz
d. f2 = 3 * f1 - 31 MHz
The intermodulation product is measured at f1 - 31 MHz.
8. This is the optimum impedance in order to achieve the performance shown
