Low Power Active Mixer Delivers 7GHz Bandwidth & 20dBm OIP3

Analog Devices LTC5562

Analog Devices announces the LTC5562, a low power, high performance active double-balanced mixer, capable of 50 Ω matching over a very wide frequency range of 30 MHz to 7 GHz. This versatile mixer can be used in either frequency upconversion or downconversion applications, with outstanding conversion gain of 2 dB. The device runs on a single 3.3 V supply rail, drawing 40 mA nominal operating current. If lower power consumption is needed, the mixer can be configured to operate as low as 15 mA, supporting a wide range of portable and transportable RF applications. Moreover, the mixer offers exceptional dynamic range performance: +20 dBm OIP3 at 3.6 GHz frequency.

The LTC5562 is offered in a tiny 10-lead, 2 mm × 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 10 μA supply current. Samples and production quantities are available immediately.
