®
LTE B3/B7 BAW Diplexer (75MHz/70MHz)
Product Overview
The QPQ1237 is a high performance Bulk Acoustic Wave
(BAW) Duplexer designed for Band 3 uplink and Band 7
uplink applications.
The QPQ1237 provides low insertion loss and high
rejection, making it an ideal choice for Small Cells. This
duplexer is housed in a compact, RoHs compliant
3.00 mm x 3.00 mm  x  0.91 surface mount pacakge (SMP).
The QPQ1237 is part of Qorvo’s extensive portfolio of RF
BAW and SAW filters.
