This Product Selection Guide contains information to help select products in the RF Multiplexers category on DigiKey.com
RF Multiplexers use bi-directional bandpass filters to combine RF signals for transmission through a single coaxial cable or to split a combined signal into separate signals for transmission through independent coax cables. Types of multiplexing include diplexing, and duplexing. triplexing, quadplexing, and quintplexing. Multiplexors are differentiated by their frequency bands, low band attenuation, high band attenuation, return loss, and mounting type.
SelectionCharacteristics
Type: The specific configuration and functionality of the multiplexer.
Frequency Bands (Low / High): Indicates the frequency ranges over which a device is intended to be used.
Low Band Attenuation (min / max dB): Minimum/typical amount by which signals at high-band frequencies are attenuated, as measured at the low-band port.
High Band Attenuation (min / max dB): Minimum/typical amount by which signals at low-band frequencies are attenuated, as measured at the high-band port.
Return Loss (Low Band / High Band): Characterizes losses due to transmission line reflections for the low- and high-frequency ports of the device.
Grade: Indicates whether the device is rated for automotive use.
Qualification: Indicates which automotive standard the device meets, if applicable.
Mounting Type : Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
