General Description
The QPQ1288 is a high performance Bulk Acoustic Wave
(BAW) filter designed to meet the strict LTE rejection
requirements for use in B40, Sub-Band 2300-2390 MHz
QPQ1288 is specifically designed to meet the high
performance expectations of insertion loss and rejection for
LTE TDD systems under all operating conditions.
The QPQ1288 uses common module packaging
techniques to achieve the industry standard 2.0 x 1.6 x 0.73
mm footprint.
Applications
For Band 40 TD-LTE applications
2300 – 2390 MHz Sub-Band
For Small Cells Base Stations

Notes:
1. All specifications are based on the QORVO schematic for the main reference design shown on page 5.
2. Average Insertion Loss is calculated by averaging |S21| in dB for each measured point within defined frequency range
3. Amplitude Variation is defined as the difference between the lowest loss and the highest loss within 10 MHz channels.
4. This is defined as the worst difference between a peak and adjacent valley within defined frequency points
5. WIFI attenuation is calculated by averaging |S21| in dB referenced to ZERO dB for each measured point within defined frequency range
6. Typical values are an average of 20 pieces measured at a temperature of 25 C.
7. Attenuation is referenced to ZER0 dB
8. Non-Linear Response is the same for Pin 2 Input
9. This is the optimum impedance in order to achieve the performance shown
