DEMO MANUAL DC2322A
Description
LTC5576
3GHz to 8GHz High Linearity
Active Upconverting Mixer
Demonstration circuit 2322A is designed for evaluation
of the
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
used with a 3.3V supply with slightly reduced performance.
The enable function allows the part to be easily shut down
for further power savings.
