Product Name : HF-ERF™ Series
The HF-ERF™ is an internally switched 3‑band, low cost, miniature, high performance tunable filter. The HF-ERF™ was designed to have the best insertion loss and Q in the smallest package possible, 2.0” x 2.78” x 0.6”. All HF-ERF™ filters are fully tested and aligned by Pole/Zero for convenience and ease of use. Both SPI and Parallel control interfaces are available in one filter. Modified variants are available upon request
