This versatile mixer can be used in either frequency upconversion or downconversion applications, with outstanding conversion gain of 2 dB. It runs on a single 3.3-V 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. Further, the mixer offers exceptional dynamic range performance of +20 dBm OIP3 at 3.6 GHz frequency and +17 dBm at 5.8 GHz
Other features include matched input frequency of 30 MHz to 7 GHz; matched LO frequency of LF to 9 GHz; differential IF frequency from DC to 7 GHz; low LO drive level of -1 dBm, low LO-RF leakage of -30 dBm at 5.8 GHz; and conversion gain of 2 dB at 5.8 GHz
The combination of low power, broadband operation and robust dynamic range makes tha LTC5562 ideal 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, 2- x 2-mm plastic QFN package. The device is rated for operation from –40°C 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.
