TJM35420XLQ,EL RF/IF and RFID

RF Transceiver ICs are widely used in various wireless applications to send and receive signals. Among them, the TJM35420XLQ,EL is one of the most advanced and reliable products. This article will explore the application field and working principle of TJM35420XLQ,EL.

The TJM35420XLQ,EL is designed for low power RF communications applications. It has a wide frequency range, up to 1400MHz, and provides a wide variety of modulation methods. Additionally, it can also be used in combination with Bluetooth, Wifi, Zigbee, and other standards. This makes the TJM35420XLQ,EL an ideal choice for low power wireless applications, such as remote controls, intercoms, and home automation systems.

The TJM35420XLQ,EL also offers a variety of different modulation types. It supports GFSK, OOK, and 2FSK / 4FSK, making it suitable for different needs. Moreover, the bit rate can be up to 150Kbit/s for GFSK and up to 250Kbit/s for 2FSK / 4FSK. The TJM35420XLQ,EL also has low power consumption and high sensitivity of -120dBm, making it a great option for short-range communications.

The working principle of TJM35420XLQ,EL is based on the direct conversion technique. This technique divides the signal frequency into two signals of the same frequency, but shifted in phase by 180°. The signals then pass through two balanced mixers, converting them to low frequency signals. Finally, the RF signal is combined with a local oscillator signal using a differential amplifier. This method is used to convert the RF signal from one frequency to another while minimizing any signal distortion.

In conclusion, the TJM35420XLQ,EL is an advanced and reliable RF Transceiver IC. It is capable of supporting multiple modulation types, high bit rates, and ultra-low power consumption, making it the perfect choice for low power wireless applications. Its working principle is based on the direct conversion technique, which allows it to convert signals without any signal loss.
