Analog Devices Inc. LTC5562 LF-7GHz Active Mixers
Analog Devices LTC5562 Active Mixers are low-power, high-performance active double-balanced mixers capable of 50Ω matching over a very wide 30MHz to 7GHz frequency range. The LTC5562 Mixers run on a single 3.3V supply rail, draw a 40mA nominal operating current, and offer a 1dB conversion gain. If lower power operation is required, the designer can configure the LTC5562 to operate with supply current as low as 15mA. When disabled, the device draws only 10μA supply current. Rated at +20dBm OIP3 with a 3.6GHz frequency, the LTC5562 Active Mixers also offer exceptional dynamic performance.
The LTC5562 Active Mixers require only –1dBm of LO power to deliver excellent noise performance with low distortion. LTC5562 maintains the impedance match for the LO input during shutdown. With a low LO leakage, the LTC5562 devices greatly reduce the need for output filtering to meet LO suppression requirements.
LTC5562’s combination of low-power broadband operation, low LO leakage, low distortion, and robust dynamic range make the devices ideal for a wide range of portable and transportable RF applications. These versatile mixers can be used in either upconverting or downconverting applications.
