PTC Launches High Sensitivity OOK /ASK Superheterodyne Receiver

(Product News, 1 Dec 2009)

The PT4302 from Princeton Technology Corp. is a single chip RF receiver designed for low power consumption, high receiving sensitivity remote control applications. The PT4302’s highly integrated design requires few external passive components, leading to savings in PCB area, and its current consumption is less then 3mA at 5V supply voltage when operating in the 315MHz frequency band.

The PT4302 integrates a low noise amplifier and a fully-monolithic PLL including on-chip VCO and loop filter, and its receiver subsystem utilizes an intermediate frequency of 10.7MHz to achieve outstanding receiving sensitivity and robust interference immunity. The PT4302 is well-suited for use in automobile/motorbike alarm systems, remote shutter control systems and lighting control systems, all of which must work reliably in electro-magnetically noisy environments. In addition, the PT4302’s built-in voltage regulator allows it to operate over a wide supply voltage range (2.4 to 5.5V). The PT4302 is housed within a small SSOP-16 package.
