Kit - Low Pass Filter Module 100W Relay Control 160-10M
Product Description
Product Description
All parts are supplied. It is the low pass filter used on the HF SuperPacker Pro 100W Amp and can also be used on other wide band amplifiers needing low pass filters.
Six relay selectable low pass filters for the HF Bands 160 - 10 Meters. The six 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. Attenuation in the stop band exceeds -40dB.
Six position rotary switch or your custom relay control circuit: 160, 80, 60/40, 30/20, 17/15, 12/10 Meters
Rated for 100W 14 Toroid inductors (T50 style) and 29 quality dip mica 500V capacitors
4.6 inch length x 2.4 inch width x 1.25 inch depth with parts mounted on both sides.
Quality circuit board with silk screen and solder mask on both sides.
Construction documentation provided on CD.
Six relay control inputs switch input and output of the selected filter.
Construction time is approximately 2 evenings.This project requires a medium skill level to complete it sucessfully. Builders require soldering, hand tool, basic electronics and component identification skills. You are required to wind the toroids according to the instructions and diagrams.

Accessories
Wound Inductor Set (with order only) This accessory provides a set of fabricated inductors for the LPF. You will still need to tin the leads and install on the circuit board but the winding is done for you. This option uses the cores supplied with the kit to fabricate the wound core set for you. Each inductor indentified for easy assembly. $65.00 |
