DC1027A

DC1027A is a demonstration circuit. It is optimized for down converting mixer tests & measurements for the input frequency range of 79MHz to 300MHz and an output frequency range of 3MHz to 67MHz, (for 12dB return loss. The LO port frequency range is 176MHz to 316MHz (10dB return loss. Demo circuit 1027A can also be optimized for HF, VHF up-converting applications. The LT® 5560 is a 0.01MHz to 4000MHz low-power, high-performance broadband Up/Down-converting active mixer. A single-ended LO source can drive this double-balanced mixer and requires – 2dBm of LO power. The signal ports can be impedance matched to a broad range of frequencies, allowing the LT® 5560 to be used as an up- or down-conversion mixer in various applications. The LT®5560 is characterized with a supply current of 10mA; however, the DC current is adjustable, which allows the performance to be optimized for each application by changing the value of resistor R1.

• Supply voltage range from 2.7V to 5.3V
• 10µA maximum shutdown current
