433MHz Superheterodyne Transmitter Receiver Kit

Description

433MHz Superheterodyne Transmitter Receiver Kit contains one receiver module Qiachip RX470C and one transmitter module Qiachip WL102-341.

The RX470C receiver is an ASK receiving and demodulating module in the UHF frequency band, supporting ASK/OOK demodulation. The receiver’s
sensitivity is as high as -108dBm, and the power consumption is very low at <6mA. The chip integrates front-end low-noise amplifier, mixer, filter, frequency synthesizer and other circuits to provide an excellent performance.

The working frequency is 433.92MHz with a bandwidth of 300kHz. The supply voltage can be in the range of 2-5V with an average current consumption of only 3.3mA at 3.3V. The maximum baud rate is 5kbps and the guaranteed operation temperature range is -40 to +85 Celsius.

The WL102-341 transmitter module is a UHF ASK modulated transmitters, supporting ASK and OOK modulation. The transmitter module integrates an analog PLL circuit and ASK modulation circuit with a transmitting power of >11dBm. It can operate on a voltage of 2-3.6V an achieve a range of up to 200m.

Receiver module dimension: 30 × 9.5 mm
Transmitter module dimensions: 16 x 12 mm

NOTE: The transmitter is a 3.3V device; only the receiver can operate at 3.3V or 5V.
