38 kHz
The IS471F is an infrared receiver integrated circuit designed for use in remote control applications. A similar function can be found in the TSOP series, such as the TSOP4838, which also acts as an infrared receiver for remote control applications, featuring similar modulation frequency capabilities. Both ICs are designed to demodulate infrared signals and are commonly used in consumer electronics.
How do you convert cellphone gsm frequency to another gsm frequency?"
The signals frequency directly.
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
315mhz
In 1738 38 is 38mhz.
it is used for reciving the infrared signal of frequency 38khz from a remote location at distance may be 10 m.
TSOP 17398 works in the sense that it is an optical transmitter that needs to be triggered by an infrared sensor in most cases. It is easy to activate.
TSOP Records was created in 1974.
TSOP - The Sound of Philadelphia - was created in 1974.

TSOP sensor is aminiaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. TSOP is the standard IR remote control receiver series, supporting all major transmission codes.
