General Description
The 885026 is a high-performance Bulk Acoustic Wave
(BAW) filter designed to meet the strict LTE rejection
requirements for use in B38.
885026 is specifically designed to meet the high
performance expectations of insertion loss and rejection
for LTE transmit systems under all operating conditions.
The 885026 uses common module packaging
techniques to achieve the industry standard 1.4 x 1.2 x
0.46 mm footprint.

Notes:
1. All specifications are based on the test circuit shown on page 3.
2. Electrical margin has been built into the design to account for the variations due to manufacturing tolerances.
3. In production, devices will be tested at room temperature to a guard-banded specification to ensure electrical compliance
over temperature.
4. At 25° only.

5. Measurement made relative to zero dB.
6. This is the optimum impedance in order to achieve the performance shown.
