RF Transceiver Modules

The SKY65266-11 is a high-performance RF Transceiver Module, which is designed for digital cellular applications. It is a module consisting of a transmitter and a receiver. The main features of this module are low power consumption, wide dynamic range, and high linearity to support digital cellular applications such as GSM, EDGE, WCDMA, HSPA and LTE.

Application Field

The SKY65266-11 is designed to support various digital cellular applications. It uses a low power RF synthesizer and a high linearity Direct-conversion Receiver (DCR) to enable low power-consumption even while supporting cellular protocols that require high linearity. It also features a high gain, low noise amplifier (LNA) and low pass filter (LPF) to ensure wide dynamic range. Additionally, the integrated narrow band polyphase filter (PBF) often used in cellular protocol receivers, such as GSM EDGE and WCDMA, is also included in this module.

Moreover, the module is also suitable for applications that require short-range communication between two digital modems. This module supports the GFSK modulation, which has an advantage over traditional modulate methods such as PSK, as it has a lower bit-error rate and features faster data processing.

Working Principle

The SKY65266-11 RF Transceiver Module operates on a wide range of frequencies, from 420 MHz to 2180 MHz. The working process can be divided into two parts: send and receive. For sending a signal, the module first uses the voltage-controlled oscillator (VCO) to generate a frequency signal. This signal is then amplified by a high gain power amplifier (HGPA) and sent to the antenna via the high power switch (HPS). The signal sent can be GMSK, EDGE, WCDMA, HSPA or LTE.

When sending signals, the module also features an automatic frequency control (AFC) circuit, which helps to compensate for frequency drifts caused by temperature changes. This allows the RF transceiver to maintain a high degree of accuracy.

When receiving a signal, the signal enters the module from the antenna and is then amplified by the LNA (Low noise Amplifier). The signal is then filtered by the LPF (Low Pass Filter) and the PBF (Polyphase Filter). This filtered signal is then converted from analogue to digital domain by the DCR (Direct-conversion Receiver). The received signal is then sent to an outdoor unit (ODU)for further processing.

The SKY65266-11 RF Transceiver Module is a very efficient and cost-effective RF transceiver module for applications such as digital cellular and short-range communication. It features many advantages, such as low power consumption, wide dynamic range, a high linearity receiver and a high gain power amplifier. This makes it an ideal solution for many digital applications.
