Datasheet

A low power, high performance active double-balanced mixer, named LTC5562 has been announced by Analog Devices. It is capable of 50Ω matching over a very wide frequency range of 30MHz to 7GHz. This versatile mixer can be used in either frequency up-conversion or down-conversion applications, with a conversion gain of 2dB. The device 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 wide range of portable and transportable RF applications. Moreover, the mixer offers exceptional dynamic range performance: +20dBm OIP3 at 3.6GHz frequency.

The LTC5562’s combination of low power, broadband operation and robust dynamic range is suitable for a wide 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, 2x2mm plastic QFN package. The device is rated for operation from -40 to 105°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 10μA supply current.
