High frequency receiver
WebIn a TRF receiver, selectivity is not constant; the receiver is more selective at the low frequency bands, while less selective at the high frequency end. Because the detector and amplifiers of a superheterodyne receiver can be designed to amplify only intermediate frequency (IF), this type of receiver is more selective and offer high fidelity (exact … WebThrough proper frequency planning, the heterodyne receiver can be made with very good spurious energy and noise performance. Unfortunately, this architecture is the most …

Many RF systems incorporate an intermediate frequency (IF) that is lower than the carrier frequency and higher than the baseband frequency. An IF-based receiver is known as a heterodyne receiver. The use of an IF simplifies the design of tunable receivers and reduces the number of components that must be compatible with high frequencies.
