Description

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ VEE, Negative Supply

These pins are VEE supply for the mixer IF output. In the

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ application PC board these pins are tied to a common

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ VEE trace with other VEE pins.

Á ÁÁÁÁÁÁÁÁÁÁÁÁÁÁ IF Output

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ The IF is a differential open collector configuration which

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ designed to use over a wide frequency range for up

conversion as well as down conversion. Differential to

Á ÁÁÁÁÁÁÁÁÁÁÁÁÁÁ single–ended circuit configuration and matching options

Á ÁÁÁÁÁÁÁÁÁÁÁÁÁÁ are discussed in the application section. 6.0 dB of

additional Mixer gain can be achieved by conjugately

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ matching at the desired IF frequency.

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ Mixer RF Input

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ The mixer input impedance is broadband 50 Ω for

applications up to 1.8 GHz. It easily interfaces with a RF

Á ÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ceramic filter as shown in the application schematic.

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ Mixer Linearity Control

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ The mixer linearity control circuit accepts approximately

0 to 2.3 mA control current to set the dynamic range of

Á ÁÁÁÁÁÁÁÁÁÁÁÁÁÁ the mixer. An Input Third Order Intercept Point, IIP3 of

Á ÁÁÁÁÁÁÁÁÁÁÁÁÁÁ 20 dBm may be achieved at 2.3 mA of control current

(approximately 7.0 mA of additional supply current).
