450-470MHz FSK version Document p/n: 9S01-7700-A201, rev. 2. Specific Requirements Overall Description 2.1. Product Perspective This Radio module version is constrained to 450-470MHz, 0dBm to 27dBm, FSK modulation and 30% maximum duty cycle. The Radio modules is to achieve full interchangeability between product model lines, maintaining mechanical and software interfaces as well as physical dimensions is a general objective. 2.1.1.
450-470MHz FSK version Document p/n: 9S01-7700-A201, rev. 2.3. Specific Requirements User Characteristics Operators: Require no knowledge of this part, all configuration is taken care of in the engineered product. Technicians: The programming of this device is effected by the connected encoder, the encoder can choose to program the device according to it’s own programming or it can take the configuration table from the eeprom on the radio module.

450-470MHz FSK version Document p/n: 9S01-7700-A201, rev. 3.4.3. Specific Requirements Power Requirements There are three power sources required for operation VBat : 5V-16Vdc @500mA The module power consumption will vary with output power. Maximum requirements for Vbat used to supply the PA will be 500mA at 27dB. during transmit. Maximum duty cycle will be <30%, typically <10% with a consequential overall reduction in average power. 3V3: 3V+- 10% @ 100mA 3V3 EEPROM : 3V+-10% @ 100mA 3.4.4.
