General Description
856990 is a high-performance RF SAW filter with a center
frequency of 403.5 MHz and bandwidth of 3 MHz
designed to provide front-end selectivity in the 402-405
MHz band. It features low loss with excellent attenuation,
and is designed to be used with a Balanced to Single-
ended operation.
I
t is ideal for short range wireless
medical data applications where small size and low power
consumption are required features. This device is RoHS
compliant and Pb-free.

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. Amplitude Variation is defined as the difference between the lowest and highest responses between 402 and 405 MHz.
6. Relative to zero dB
7. This is the optimum impedance in order to achieve the performance shown
