ZM357S-USB-LR

RF Receiver, Transmitter, and Transceiver Finished Units

The ZM357S-USB-LR is a unit that combines an RF transmitter, receiver, and transceiver into a single finished unit. It is a cost-efficient solution for applications that require unified devices. This device is useful in a number of different scenarios since it not only has the capacity to transmit and receive, but also to transceive (send and receive). By integrating all of these features into one device, users can save both space and money.

Application Field

The ZM357S-USB-LR is ideally suited for applications where transmitting, receiving, and transceiving are all necessary. Examples include radio astronomy applications, remote-controlled machines, digital communication systems, satellite communication systems, and digital TV transmissions. It can also be used in wireless communications networks, such as those used in wireless local area networks (WLANs), cellular phones, and personal communications services (PCS).

Working Principle

The ZM357S-USB-LR operates by using a direct conversion radio frequency (RF) receiver. This type of receiver uses a single voltage controlled oscillator (VCO) to convert an incoming RF signal to an intermediate I/Q signal, which is then demodulated to obtain the original information. The I/Q signal is output as a digital pulse-code modulation (PCM) signal, which is then output through a USB port.

The transceiver portion of the device works by sending out the required radiofrequency power needed to transmit data over a wider range. The power output is adjustable, allowing the user to choose the appropriate level for the application. The receiving portion of the device then receives the incoming radio-frequency signals and amplifies them so they can be processed by the transceiver. The transceiver then outputs the received data by encoding it into a digital signal.

Conclusion

The ZM357S-USB-LR is a versatile unit that is capable of transmitting, receiving, and transceiving data. This unit is ideal for a range of applications that require unified devices, as it can save both space and money. The working principle of the device is based on the direct conversion radio frequency receiver, which enables it to receive, amplify, and transcode incoming radiofrequency signals. This versatility and cost effectiveness makes the ZM357S-USB-LR a great choice for a range of applications.
