Notes:

1.

All specifications are based on the TriQuint schematic for the main reference design shown on page 3

2.

An external impedance matching network with ±2% tolerance will be necessary to achieve the proposed specifications

3.

In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over

temperature

4.

Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances

5.

Typical values are based on average measurements at room temperature

6.

This ripple is defined as the worst peak to adjacent valley within specified frequency range

7.

Passband Flatness is defined as the difference between maximum and minimum loss over the specified band

8.

The EVM specification is guaranteed by design and measured approximately in production

9.

2.0 db Band edges are relative to Minimum Loss

10. All Bandwidth and Attenuation measurements are relative to loss at 1dB Center Frequency

11. This is the optimum impedance in order to achieve the performance shown
