Compensated Surface Acoustic Wave (TC SAW)
duplexer designed to meet the strict LTE requirements
for use in Band 13.
857181 is specifically designed to meet the high
performance expectations of insertion loss, isolation
and BC14 rejection in LTE systems operating in B13
applications under all operating condition.
The 857181 uses common packaging techniques to
achieve the industry standard 2.5 x 2.0 mm footprint.

Uplink to Downlink Isolation
Notes:
1. All Specifications are based on the TriQuint schematic for the main reference design shown on page 4
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. Amplitude Variation is defined as the difference between the lowest loss and the highest loss within defined frequency
points
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 Downlink band is measured. The first tone is applied to the Uplink 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
