EME199 Series Filter Kits

EME199 Description:

The Mini-Kits EME199 PC Board has been designed for constructing simple filters using SMD components, and fits into a Hammond 1590A enclosure. Kit part numbers are prefixed for filter type, ( LPF Low Pass, BPF Band Pass or HPF High Pass ), the number after is the filter order, followed by the band or frequency in MHz. These filters are easy to construct, and require minimal alignment if constructed as per the Kit notes.

Please Note: These filters are designed for receiver applications only and are not designed for transmitting power over +20dBm 100mW through. Many older Transceivers has a receiver loop through on the back panel that can be used to connect to external filters.

LPF9-0M5 Kit Notes:

The LPF9-0M5 is a 9th order 500kHz low pass filters and has been designed to rduce overload to NDB receivers from overload or inter modulation caused by very high AM broadcast band signals. The filter uses a number of SMD components that are easily fitted to the board. The filter essentially is no tune, and no alignment or test equipment is required. The filter is ideal for many low cost SDR receivers that suffer for overload.

BPF9-1M8-30M Kit Notes:

The BPF9-1M8-30M consists of 9th order 1.8MHz high pass, and 30MHz low pass filters, and has been designed to protect HF receivers from overload or inter modulation caused by very high AM and FM broadcast band signals. The filter uses a number of SMD components that are easily fitted to the board. The filter essentially is no tune, and no alignment or test equipment is required. The filter is ideal for many low cost SDR receivers that suffer for overload.

BPF9-1M8-75M Kit Notes:

The BPF9-1M8-75M consists of 9th order 1.8MHz high pass, and 75MHz low pass filters, and has been designed to protect HF receivers from overload or inter modulation caused by very high AM and FM broadcast band signals. The filter uses a number of SMD components that are easily fitted to the board. The filter essentially is no tune, and no alignment or test equipment is required. The filter is ideal for many low cost SDR receivers that suffer for overload.
