DESCRIPTION
The LTC 5562 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. Demon-
stration 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 trans-
mission-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
