What is rf loop back?
RF Loop Back ,Usually used in all RF Transceivers to covert the Transmitted signal into the Receiver frequency ,checking the Overall performance of the Terminal .This is an Option useful only in maintenance and not recommended BY Standard Authorities (Fcc, ETSI, etc )
What is RF scanning?
Depending on how it is used, it can have different applications. However, RF scanning is where one runs a receiver through a series of radio frequencies (RF), and tries to identify a specific frequency. It can include illegal operations, such as RF scanning wherein a transmitter is used to transmit a scan to interfere with transmitters such as petrol pumps, or scanning to locate cell or wireless telephone transmissions. Or there can be harmless applications such as simply tuning a radio manually.
What is the function of the RF amplifier?
rf is a single tuned amplifier . Its functions are :- 1.improves selectivity ( i.e rejection of unwanted signal) , so that it prevents heterodyning which results in interference frequency. 2. improves image frequency rejection 3. improves sensitivity ( gain of amplifier ) 4.improves coupling of receiver with antenna . 5. improves signal to noise ratio. 6. reradiation of local oscillator through receiver antenna is prevented
RF amplifier of an AM receiver is normally biased in class a class b class c?
class C because Class C also provides better signal,rejects unwanted signal.class c

What is rf transmitter
RF amplifier of an AM receiver is biased in?
class C
What is range of rf transmitter and receiver?
depends on frequency and power
What is RF tracking as compared to satellites?
I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.

How are gps' made?
using custom digital signal processing circuits, at least one standard microprocessor, and fancy RF receiver circuits.
What is dynamic range in rf receiver?
Dynamic range in an RF receiver refers to the range of signal amplitudes that the receiver can effectively process without distortion or loss of performance. It is typically defined as the ratio between the largest and smallest signals the receiver can handle while maintaining a specified level of performance, usually measured in decibels (dB). A high dynamic range indicates the ability to distinguish weak signals in the presence of much stronger ones, which is crucial for effective communication in environments with varying signal strengths.
What is Double conversion receiver?
A type of superheterodyne radio using two separate mixers, each producing its own intermediate frequency. The block diagram of such a receiver is like this: RF -> M1 -> IF1 -> M2 -> IF2 -> D -> AF

Draw and explain the super heterodyne receiver?
A superheterodyne receiver is a type of radio receiver that converts a high-frequency signal to a lower intermediate frequency (IF) for easier processing. It employs a mixer to combine the incoming radio frequency (RF) signal with a locally generated oscillator signal, producing the IF. This allows for improved selectivity and sensitivity through the use of filters and amplifiers. The basic components include an antenna, RF amplifier, mixer, local oscillator, IF amplifier, detector, and audio amplifier.

How do you detect a RF transmitter148-151MHZ within 5oo meters range and locate it?
Use a scanner or other portable VHF receiver, with an external directional antenna such as a loop or Yagi.
