Double balanced mixer runs on single 3.3V supply rail

The LTC5562 is a low power, active double-balanced mixer, capable of 50-Ohm matching over a wide frequency range of 30MHz to 7GHz. This versatile mixer can be used in either frequency up conversion or down conversion applications, says Analog Devices with conversion gain of 2dB.

The LTC5562 runs on a single 3.3V supply rail, drawing 40mA nominal operating current. If lower power consumption is needed, the mixer can be configured to operate as low as 15mA, supporting a range of portable and transportable RF applications. The mixer offers +20dBm OIP3 at 3.6GHz frequency dynamic range performance.

According to Analog Devices, the LTC5562’s combination of low power, broadband operation and robust dynamic range is suitable for a range of mobile applications such as portable test instruments, battery-powered public safety and emergency radios, military manpack radios, portable modems, broadband access points and small cells, license-free band radios, remote controls, broadcast radios and UAV/drone radios.

The LTC5562 is offered in a tiny 10-lead, 2.0 x 2.0mm plastic QFN package. The device is rated for operation from -40 to +105 degree C case temperature. An enable pin allows an external controller to shut down the mixer for extra power savings. When disabled, the device typically draws only 10-microA supply current.

Samples and production quantities are available immediately.
