TACTICAL RADIO GEAR, LLC
HF Single Band Bandpass Filters
BPF-200 Economical 200W Band Pass Filters
Amateur Radio, Military HF, Commercial HF, and Marine Communications system
Made in the USA
Bandpass filters are essential, in preventing receiver front end damage during multiple HF radio operation. Tactical Radio filters are available for all HF amateur bands, including 6 & 2 meters. All models are supplied with UHF Female/SO-239 connectors; N-connectors can be substituted.
Designed to provide a roll-off outside each Amateur band; these filters bring the benefit of a dramatically lower noise floor; for improved single-band, weak signal reception; necessary for contest and Field Day operations; or simply crowded band conditions! These compact HF Transmit/receive filters, accomplish out-of-band suppression, which effectively eliminates noise and interfering signals. Simply place the filter in-line between transceiver, antenna or an amplifier.
If you are planning a DXpedition, a contest, or simply need the enhanced performance that a bandpass filter can provide, your radio needs these filters. Tactical Radio Gear, filters are the most cost-effective, single band filters on the market. The cutting-edge advantages, that these exceptional filters can provide; to improve image, and intrusive harmonic problems, for mono-band, multi-radio contest settings cannot be overstated.
Tactical Radio Gear, filters are essential for use with transmit multiplexers, as these filters will augment the separation needed to tolerate multiple radios on different bands at the same time - on the same antenna.
When used in combination with multiplexers; known as multi-band transmit combiners; it is essential for each multiplexer band to provide the additional isolation necessary to allow the operation of multiple transceivers; all transceivers in a particular situation, can operate in chorus, unhindered by the signals from radios operating on the other bands - or even on the same antenna.
The Tactical Radio, BPF-200 series filter design, is based on a 3-pole filter configuration(s), that maintains a 50 Ohm impedance, and low insertion loss.
These HF Transmit/receive Bandpass Filters, are of tremendously high-quality, and precisely designed to limit the RF bandpass to a single Amateur band.
Inputs and outputs are at DC ground potential. Hi-Q Precision Silver Mica capacitors, and heavy-duty inductors, are used in the L/C tuned circuits.
Each filter is assembled, and individually tuned on a state of the art testing system.

VSWR & POWER CONSIDERATIONS
Hi VSWR will generate damaging RF voltages, and currents in a bandpass filter. VSWR is a reality that we have to be attentive to; and Tactical radio gear, has made every effort, to protect the filter components from these potentially damaging forces.
These designs are over-engineered, with vigilant consideration to component selection. No expense was spared to insure the reliability and performance of our filters.
The weak-link in most Bandpass filters; at these power levels, in a high VSWR condition, are the capacitors. Tactical Radio Gear, uses High-Frequency, High-Power, High-Voltage, Silver Mica capacitors; ideal for use where multilayer ceramic caps are not recommended because of cracking.
The natural mica dielectric retains it’s extremely high-Q to many megahertz; and is free from thermal cracking. Silver Mica capacitors are Ideal for tuned L/C Circuits & High RF current.
Unlike NPO ceramic capacitors, these capacitors are rock stable - no change with time, V & f and a temperature Range of -55 ºC to +125 ºC. Individual capacitance Tolerance: ±5% @ 500 Vdc. While RoHS Compliant.
All the inductors in our filters are wound with the largest possible gauge wire, consistent with sensible design practices. Depending on the band, the toroid cores when used, are selected for the largest gauge wire, and minimum turns, to minimize IR losses/heating.
Notwithstanding the robust design, operator(s) should endeavor to maintain a minimum VSWR when using these filters.
Tactical Radio Gear, BPF-200 model filters, are designed for use with 100W/200W PEP transceivers.
Note:
The BPF-200 filter(s) can be operated @ a 100% duty cycle. SSB speech (50% duty), CW average power is roughly equivalent to speech.

                                                            NEW PRODUCT ANNOUNCEMENT
Band Pass Filter ‘BY-PASS’ accessory. Two versions: Single filter and four filters. This product has been something that has been need for a long time. The ability to remotely switch a filter in/out of the radios output coax-line. Mono band filters only allow the radio to function on the frequency that the filter is designed for; making it necessary to disconnect the filter if you want to operate on a different band! This can be annoying!  Occasionally the operator attempts to use their radio on a band other than the filter(s)? This can have catastrophic results, depending on the radio and the operators’ response to the mistake.
This product allows the filter to be quickly/easily switched out of line, by-passing the filter completely. Rated for 200W, the by-pass feature presents a flat VSWR to the radio. The installation only takes a few minutes, and requires no additional connections; other than the provided control/power cable. In the power off position, the By-Pass feature automatically defaults to the by-pass mode.
