General Description
856931 is a high-performance Surface Acoustic Wave
duplexer designed to meet the strict LTE requirements for
use in Band 17.
The 856931 is specifically designed to meet the high
performance expectations of insertion loss, isolation and
linearity in LTE systems operating in Band 17 applications
under all operating conditions.
The 856931 uses common module packaging techniques to
achieve the industry standard 2.5 x 2.0 mm
2
footprint. The
duplexer exhibits excellent power handling capabilities.

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
temperature
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. Relative to zero dB
6. This is the optimum impedance in order to achieve the performance shown

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. Relative to zero dB
6. 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 = 704 to 716 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 = 30 MHz
b.
f2 = 2 * f1 + 30 MHz
c.
f2 = f1 - 30 MHz
d.
f2 = 3 * f1 + 30 MHz
The intermodulation product is measured at f1 + 30 MHz.
7. This is the optimum impedance in order to achieve the performance shown
