Product Description

Description:
The CY121 is an ASK/OOK/FSK compatible super heterodyne wireless receiving module with high performance for ISM frequency band. With the adoption of European brand RF wireless data transferring/receiver chipsets, the module has advantages at high receiving sensitivity, small size and low cost. It solves the problem on space for the small-sized product. From wireless signal input to data output can be done without any electrical circuit. User only use extra simple data decode circuit can achieve wireless products development.

Features:

1. Frequency: 300M - 960M (ASK/FSK);
2. High sensitivity -109dBm;
3. Supply voltage: 3.6V - 5.5V;
4. Operating temperature: -30ºC +85ºC, work normally even in the severe temperature environment;
5. Excellent inhibiting ability for local oscillator radiation: multiple receivers receive signals from one transmitter simultaneously without any mutual interference and influence on range;
6. Dimension: 31.5*12*5mm;
