The Global Reach of Local Innovation
Originating right here in Angola, NY, our engineers sought to solve persistent challenges faced by radio networks. These once-groundbreaking technological innovations have become the standard solution for communication towers and networks globally. Over the years, TX RX Systems has continued to push the boundaries of RF technology, securing several patents that have had a transformative impact on the industry.
Failure Responsive Alternate Amplifier and Bypass System for Communications Amplifier
Inventor: Daniel P. Kaegebein
Filed: March 1, 1994
Issued: May 23, 1998
A communications amplifier system which includes a primary preamplifier circuit, a secondary preamplifier circuit and a bypass circuit mutually exclusively selectable through a relay switching means which is automatically activated to bypass the primary preamplifier with the secondary preamplifier or the secondary preamplifier with the bypass circuit in the event of malfunction. In the standby mode, the secondary preamplifier is not connected to DC power or RF signal input.

Issued: January 21, 1986
A communications tower mounted amplifier system which includes a primary preamplifier circuit, a backup preamplifier circuit, and a bypass circuit mutually exclusively selectable through a relay switching means remotely controllable for bypassing the primary preamplifier with the backup preamplifier or the bypass circuit in the event of malfunction. The system includes an AC-to-DC power source and a backup battery system.
Bi-directional Filter System for Amplifying Signals in Separate Frequency Bands
Inventor: Daniel P. Kaegebein
Filed: May 9, 1980
Issued: February 23, 1982
A two way repeater-amplifier for amplifying one or more signals of a first group propagating in a first direction and one or more signals of a second group propagating in the opposite direction is proposed. The repeater-amplifier utilizes a single amplifier disposed to receive signals from first and second filter networks adapted to pass signals within the first and second groups respectively. Third and fourth filter networks are disposed to receive signals from the output of said amplifier and are adapted to pass signals within the second and first groups respectively. Tuned cables cooperate with the networks to route only the first signals through the first network, the amplifier and the fourth network, while other tuned cables cooperate with the networks to route only the second signals through the second network, the amplifier and the third network.
Notch Filter Network
Filed: August 22, 1977
Issued: January 29, 1980
Inventor: Daniel P. Kaegebein
An electrical filter network with improved characteristics is disclosed for selectively attenuating and passing two different, closely spaced frequencies. The notch filter network includes a low Q reactive circuit tuned to be parallel resonant at the frequency to be attenuated. A cavity resonator with a high Q is inductively coupled to the reactive circuit and is tuned to be resonant at the frequency to be passed. Utilizing these concepts, a multicoupler may be constructed to consist of two or more such filter networks in combination with a transmission line. In such a multicoupler, the network adjacent to the antenna terminal is separated therefrom by a multiple of a half wavelength. Additional filter networks are separated from one another by an odd number of a quarter wavelength. With this arrangement, each network passes a band around the frequency to which the high Q cavity is tuned and rejects a band of frequencies around the reactive circuit resonant frequency.
Series Multicoupler and Notch Filter Utilizing Same
Inventor: Daniel P. Kaegebein
Filed: October 20, 1978
Issued: June 3, 1980
An R.F. resonant cavity filter for connection in a transmission line and multicouplers utilizing same, said filter adapted to pass only signals of a predetermined frequency into and out of a branch transmission line, to block signals of said predetermined frequency from propagating down said transmission line in one direction but not the other, and to pass all other signals substantially undisturbed.
Comb-Line Filter
Inventor: Daniel P. Kaegebein
Filed: March 5, 1997
Issued: September 15, 1998
A comb-line filter incorporating a plurality of bandpass resonators set off center between ground planes is provided with input and output coupling means comprised of dual notching resonators.
It is a primary objective of the present invention to provide a comb–line filter with dual notch resonator inputs and outputs arranged such that the individual notch resonators will not couple to one another.
