10 Band 6 Position Low Pass Filter, HF Packer Amp V4
Product Description
Introduction: This is the 10‐Band Filter Module for the HF Packer Amp Model V4.
Specifications:
• Size: 3.8 x 2.4 inch
• 10 Band, 6 position: 160‐10M (160, 80/75, 60/40, 30/20, 17/15, 12/10)
• Performance: greater than ‐40dB Rejection in the stop band
• Power Rating: 50W
• Control: Miniature front panel mount switch attached to the circuit board. Requires 12V, 15mA
• Mating connectors included
Description: The design features a compact 4-layer circuit board with relay selection of the filter input controlled by a panel mount miniature rotary switch attached to the Filter Module circuit board. Using input relay switching provides greater isolation and performance with less dense component assembly. The 6 filters cover 10 bands. For example, the 30-20M filter uses 3 pi-sections to provide good roll-off of the 20 meter 2nd harmonic while operating on 30 meters. Most of the filters are elliptic, aiding attenuation of specific harmonics but not needed on 160 and 80 meters since each covers only one band. The kit includes all the parts and circuit board. The comprehensive download construction manual guides the builder through each step of assembly. The instructions for winding inductors include a unique clock face chart to show wire spacing information. Guided assembly steps minimize assembly error.
If you order the fabricated coil set option with this order, we sweeten the deal by fabricating and mounting the inductors and transformers on the amp and providing a fabricated cable set for the LPF.
