General Description
Uplink IF filter specifically designed for the demanding
requirements of 4G wireless infrastructure systems.
Designed for versatile drive configurations, this filter is
optimized for a balanced input and output, leading to
elimination of baluns.
Low insertion loss, excellent attenuation and flat in-band
performance leading to low EVM contribution, makes this
filter an effective choice for our customers LTE and Multi-
standard platforms.

Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 3
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
4. Typical values are based on average measurements at room temperature
5. Relative to insertion loss at center frequency
6. Amplitude Ripple is defined as the worst case difference between a peak and an adjacent valley within defined frequency points
7. This is the optimum impedance in order to achieve the performance shown
