General Description
The 885075 is a high-performance, high power Bulk
Acoustic Wave (BAW) Tx/Rx filter designed to meet the
strict LTE rejection requirements for use in B40.
The 885075 is specifically designed to meet the high
performance expectations of insertion loss and rejection
for LTE transmit systems under all operating conditions.
The 885075 uses common module packaging
techniques to achieve the industry standard 1.1 x 0.9 x
0.50 mm footprint. The filter exhibits excellent power
handling capabilities.

Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 3. Min/max is being
specified over −20 to +90 °C.
2. Typical values are derived through integration of the linear s-parameter over the indicated band at +25 ºC.
3. Integration of linear s-parameters over an 18MHz sliding frequency span.
4. H2 is measured for Pin=28 dBm (CW) at room temperature.
