General Description
The 885043 is a high-performance Bulk Acoustic Wave
(BAW) Tx filter module designed to meet the strict TD-LTE
rejection requirements for use in B38 and B40.
885043 is specifically designed to meet the high performance
expectations of insertion loss and rejection for TD-LTE
receive systems under all operating conditions.
The 885043 uses common module packaging techniques to
achieve the industry standard 1.7 x 1.3 x 0.46 mm footprint.
