Description

The LTC®5562 is a versatile low power mixer optimized for applications requiring wide input bandwidth, low distortion and low LO leakage. This mixer can be used for either upconverting or downconverting applications, and provides a nominal conversion gain of 1dB. The differential input is optimized for use with a 1:1 transmission-line balun, the input is 50 broadband matched from 30MHz to 7GHz.

The LO can be differential or single-ended and requires only –1dBm of LO power to achieve excellent distortion and noise performance. The impedance match at the LO input is maintained during shutdown. This mixer offers low LO leakage, greatly reducing the need for output filtering to meet LO suppression requirements.

The LTC5562 uses a 3.3V supply for low power consumption and the enable control allows the part to be shut down for further power savings. The total mixer current is adjustable, by simply adding a resistor in series with the LGND pin, for applications requiring even lower power.
