EZ/EQ Surface Mount Devices

Marki Microwave EZ and EQ Carrier Surface Mount Mixers are designed for easy surface-mount integration into

microwave radio and other wireless systems for applications up to 30 GHz.

EZ/EQ-Carrier Surface Mount components may be mounted one of two ways: reflow-soldered directly to the

system substrate, or screwed in place and solder-tacked at the port and ground connections. For many

applications, it is sufficient to simply solder- tack the input/output and ground connections. 0-80 metal or nylon

screws may be used for alignment. Nylon screws will minimize radiation effects.

For best performance, the surface mount mixer is reflow-soldered to the circuit board as shown. The

mounting holes can be used for alignment, however screws are not required. See Application Note 601-03688

for the recommended PCB system footprint.

Note that EZ-Carrier T3As and EZ/EQ-Carrier Buffer Amplifiers are not suitable for reflow solder due to the

use of open amplifier chips.

For EZ/EQ Amplifiers and EZ T3As, silver epoxy attach the EZ/EQ-carrier and solder the eyelets for the

input/output and bias. Alternately, screws can be used for the carrier attach, no silver epoxy needed, with the

eyelets soldered as before. The maximum allowed temperature for EZ/EQ Amplifiers and EZ T3As is +120ºC.
