The LTC5510IUF#PBF is a 1MHz to 6GHz wideband high linearity Active Mixer optimized for applications requiring very wide input bandwidth, low distortion and low LO leakage. The chip includes a double-balanced active mixer with an input buffer and a high speed LO amplifier. The input is optimized for use with 1:1 transmission line baluns, allowing very wideband impedance matching. The mixer can be used for both up- and down-conversion and can be used in wideband systems. The LO can be driven differentially or single-ended and requires only 0dBm of LO power to achieve excellent distortion and noise performance, while also reducing external drive circuit requirements. It offers low LO leakage, greatly reducing the need for output filtering to meet LO suppression requirements. The LTC5510 is optimized for 5V but can also be used with a 3.3V supply with slightly reduced performance. The shutdown function allows the part to be disabled for further power savings.
