Dependent upon the type of combiner it may introduce additional loss by using resistors, or it may be use transformers in which case it could in theory be lossless. RF combiners can be used in a number of different applications. They are used for sending several signals along a single ...
The Contemporary Research QCA9-33 is an active RF combiner that features eight high-level inputs and one low-level input, combining with high isolation, and amplifying up to a 33 dBmV output level. Designed for QMOD HDTV applications, the eight RF inputs typically receive 29 dBmV RF from...
The RF combiner combines the output power from each of the sub-amplifiers through output electrical paths, and provides the combined power to the power amplifier output. The output electrical paths from the sub-amplifiers to the power amplifier output are substantially physically identical. 展开 ...

(before thepower combiner) be at least 60 dB; in the probe itself, it must be much higher, say, 180 dB. This drastic increase of the on–off ratio is assured by the use of class C driver and power amplifiers. Traditionally double-balanced mixers are used as rf gates: they are fast...
