50-500 MHz IF Reference Design

TQP3M9035 performance may be optimized for IF operation below 500 MHz by making suitable adjustments to the

value of the bias inductor L1 and the DC blocking capacitors C1 and C2. When using the TriQuint evaluation board be

sure to match the value of C5 and C6 to that of C1 and C2 for accurate loss de-embedding.
