Bias tees allow the insertion of DC voltages into a signal path without disrupting the existing signal in that path.
|
|
DC blocks are used to prevent DC energy from flowing through sensitive RF components.

RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.

|
Electrical terminators are installed at the end of a bus or transmission line to prevent signals from reflecting back. Sometimes called electrical terminators, these devices are used to prevent electrical interference.

|
Frequency meters are instruments that provide analog outputs as frequencies that vary as a function of the applied input. They display values on a dial, usually with a needle or moving pointer.
|
|
RF power dividers and power combiners are circuits that accept an input signal and deliver multiple outputs equal in phase and amplitude. In hybrid varieties, the signal is split into different phases with equal amplitude.
|
|
RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB).
|
|
RF couplers are circuits that sample RF transmissions by combining (coupling) signals asymmetrically. There three basic types of devices: unidirectional, bidirectional, and dual directional.
|
|
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters.
|
|
RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal.
|
|
RF terminators are used to absorb energy and prevent RF signals from reflecting back from open-ended or unused ports.
|
|
RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.
|
|
Waveguide terminators absorb energy and prevent RF signals from reflecting back from open-ended or unused waveguide ports.
