QPQ1286
®
TDD B40 BAW Band Pass Filter (50MHz)
General Description
The QPQ1286 is a high-performance Bulk Acoustic Wave
(BAW) filter designed to meet the strict LTE rejection
requirements for use in B40, Sub-Band 2320-2370 MHz
QPQ1286 is specifically designed to meet the high-
performance expectations of insertion loss and rejection for
LTE TDD systems under all operating conditions.
The QPQ1286 uses common module packaging
techniques to achieve the industry standard 2.0 x 1.6 x 0.73
mm footprint.
3 Pin 2 x 1.6 mm leadless SMT Package

Notes:
1. All specifications are based on the QORVO schematic for the main reference design shown on page 4
2. Amplitude Variation is defined as the difference between the lowest loss and the highest loss within defined frequency points
3. This is defined as the worst difference between a peak and adjacent valley within defined frequency points
4. Typical values are and average of 20 pieces measured at a temperature of +25 °C
5. Attenuation is referenced to ZERO dB
6. Attenuation is referenced to ZERO dB
7. This is the optimum impedance in order to achieve the performance shown
