DEMO MANUAL DC2322A

Description

LTC5576

3GHz to 8GHz High Linearity

Active Upconverting Mixer

Demonstration circuit 2322A is designed for evaluation

of the LTC®5576 active upconverting mixer with very

wide input bandwidth and low distortion. Its OUT port

is optimized for 4GHz to 6GHz applications, but is easily

retuned for output frequencies as low as 3GHz, or as high

as 8GHz with minor performance degradation. The IN port

is optimized for 30MHz to 6GHz operation while the LO

port is always 50Ω matched from 1GHz to 8GHz.

The LTC5576 is optimized for 5V operation, but can be

usedwitha3.3Vsupplywithslightlyreducedperformance.

The enable function allows the part to be easily shut down

for further power savings.
