Maxim 推出低功耗超外差接收器 MAX7034,用于接收300MHz～450NHz 频率范围内的 ASK 数据。器件集成了LNA、镜频抑制混频器、内置 PLL 模块、带有接收信号强度指示(RSSI)的10.7MHz IF 滤波器以及模拟基带数据恢复电路,仅需少量的外部器件即可实现完整的接收器方案。为保证在汽车和消费类应用中具有优异的接收灵敏度,器件的关键模块均设计为能够承受高温。MAX7034具有114dBm 的高灵敏度和44dB 的镜频抑制,是遥控钥匙门禁系统、汽车报警、家庭安防系统、遥控和车库开门器等应用的理想选择。
Maxim introduces the MAX7034, a low power superheterodyne receiver that accepts ASK data in the 300MHz to 450NHz frequency range. The device integrates an LNA, a video rejection mixer, a built-in PLL module, a 10.7MHz IF filter with Received Signal Strength Indication (RSSI), and an analog baseband data recovery circuit that enables complete reception with only a small number of external components Program. To ensure excellent receive sensitivity in automotive and consumer applications, the device’s key modules are designed to withstand high temperatures. With high sensitivity of 114dBm and image rejection of 44dB, the MAX7034 is ideal for applications such as remote keyless entry systems, car alarms, home security systems, remote controls and garage door openers.
