MAX7030_V4中文资料美信数据手册PDF规格书

General Description

The MAX7030 crystal-based, fractional-N transceiver is designed to transmit and receive ASK/OOK data at facory-preset carrier frequencies of 315MHz, 345MHz†, or 433.92MHz with data rates up to 33kbps (Manchester encoded) or 66kbps (NRZ encoded). This device generates a typical output power of +10dBm into a 50Ω load, and exhibits typical sensitivity of -114dBm. The MAX7030 features separate transmit and receive pins (PAOUT and LNAIN) and provides an internal RF switch that can be used to connect the transmit and receive pins to a common antenna.
