In stock.The receiver test methods stipulated in 300-220 are fairly straightforward, although for 'old school' RF engineers used to measuring absolute sensitivity and then relating rejection specs to that there is a surprise: EN300-220 specifies in terms of absolute interferer levels, not relative values: Sensitivity.In the above table, a VSWR of 4 has 36% of power delivered by the receiver reflected from the antenna (64% of the power is delivered to the antenna). Note that a reflected power of 0 dB indicates all of the power is reflected (100%), whereas -10 dB indicates 10% of the power is reflected. If all the power is reflected, the VSWR would be infinite.

Editorial Team - everything RF. Mar 11, 2022. A Direct-Conversion Receiver (DCR), also called Zero-IF receiver, is a type of receiver in which the Intermediate Frequency (IF) conversion stage is not present. The signal intercepted by the receiving antenna is converted directly from RF to baseband using synchronous detection driven by a local ...

3.4.1 Radio as a Cascade of Two-Ports. The front end of an RF communication receiver or transmitter combines a number of subsystems in cascade. The design of the RF front end requires trade-offs of noise generated by the circuit, of frequency selectivity, and of power efficiency, which translates into battery life for a communication handset.

Images and Spurious Signals. There are secondary trade-offs in these options as well. For example, zero-IF introduces LO leakage and I/Q mismatch image terms, 2 while RF sampling introduces interleave spurs 3 due to mismatches within the converter architecture, as well as RF harmonics in the converter and sample-related jitter terms. 4 The good news is that most images and spurious signals are ...check (Required, int): The 4-bit check to listen for.

On the higher HF bands (particularly 21, 24, and 28 MHz), cables and wires begin to look like antennas as their lengths exceed ⅛ wavelength. A 6-foot data cable, for example, is about 3/16 wavelength long on 28 MHz ...Taking into account the 40dB pad, we now know the effective sensitivity of the receiver on-site is 100µv - 40dB or 1µv of effective sensitivity. 1µv instead os 0.25µv! This shows the noise floor at your repeater site is 10dB worse than the receiver sensitivity on the bench. No wonder those HTs have problems getting in!

(E.g. when the receiver sensitivity goes from -90 dBm to -60 dBm, it has become less sensitive). A ten fold increase in bandwidth - for example from 10 kHz to 100 kHz - reduces the sensitivity by 10 dB.
