I suspect you mean an "Intermediate Frequency transformer", or IF transformer.
Superheterodyne (Or superhet) receivers convert the frequency of an incoming signal to a special frequency called the "Intermediate Frequency" or "IF". Most of the amplification takes place in the IF Amplifier which usually has several stages. Each of these stages is coupled to the next stage by a tuned transformer called an IF transformer.
For AM receivers, the Intermediate frequency is usually 455 KHz, and for FM receivers it is usually 10.7 MHz.
These Transformers are usually about 20 turns of Litz wire on a plastic former with a dust-iron adjustable core. It sits in a little metal shield can.
What else can I help you with?
Why is intermediate frequency transformer used in amplitude modulation?
used as a adjustable band pass filter...
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the difference between isolation transformer and ferromagnetic transformer?
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
Why auto transformer is lighter than conventional type?
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
What is the function of intermediate frequency transformer?
intermediate frequency transformer (ift) acts as a band selective n/w. the ift which is 455 khz is then given to IF amplifiers which is then given to detector.

Can you put transformers in series to double your voltage?
You can if done carefully. The neutral of one transformer must be set up to be at the positive voltage of the other transformer. This might require an intermediate step transformer that is center tapped (so three instead of 2 transformers).
Are intermediate frequency transformers are step up transformers?
Intermediate frequency transformers can be either step-up, step-down, or 1:1. The term "intermediate frequency" relates to the frequency of operation, and not to the voltage or current conversion ratios. An "intermediate frequency transformer" is a special purpose transformer used for filtration purposes in radio reception, rather than voltage or current conversion, though a step-up or step down turns-ratio may be used in the design.
How to step down 15kiloV to 20V for practical purposes?
Stepping down AC voltage is accomplished using a transformer. In your case the primary (15kV) to secondary (20v) ratio is 750, which is very high for a typical transformer, so I suspect you would need to step down to some intermediate voltage, and then use a second transformer to step down to 20 volts.
What is a half transformer and a half transformer?
a hole transformer
Why induction transformer called rotating transformer?
Transformer has windings
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is the function of fans in transformer?
The function of fans in a transformer is to regulate the transformer's temperature.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
What is the best intermediate in New Zealand?
The best Intermediate in New Zealand is MAIDSTONE INTERMEDIATE
