LTC5562是一款通用型低功率混频器，专为要求宽输入带宽、低失真和低LO泄漏的应用而优化。该混频器可用于上变频或下变频应用，并提供一个1dB的标称转换增益。差分输入专为用于1:1传输线路巴伦而优化，输入在30MHz至7GHz范围内具有50Ω宽带匹配。

LO可以是差分或单端，并且只需要–1dBm的LO功率就能实现卓越的失真和噪声性能。LO输入端上的阻抗匹配在关断期间得到保持。这款混频器可提供低LO泄漏，大幅减少了输出滤波满足LO抑制要求的需要。

LTC5562采用一个3.3V电源以实现低功耗，而且启用控制可使器件关断以进一步节省功率。总的混频器电流可通过简单地增设一个与LGND引脚串联的电阻器进行调节，以适合要求更低功率的应用。

DC2483A-B：LTC5562 - Low Power Mixer Demo Board Set Up for Downconversion Applications with IF Output Turned to 10MHz to 550MHz

The LTC5562 is a versatile low power mixer optimized for applications requiring very 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. Demonstration circuit 2483A-A showcases the LTC5562 mixer for upconverting applications while demonstration circuit 2483A-B is tuned for downconverting applications. The differential inputs are optimized for use with 1:1 transmission- line baluns, allowing very wideband impedance matching. The LTC5562 uses a 3.3V supply for low power consumption and an enable pin allows the part to be shut down for further power savings. The total mixer current is adjustable, allowing for even further power savings. The standard match frequency ranges for each board are outlined in the table below.
