NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
General Notes:
1. The DMG-B series surface mount Double Balanced Mixers covers the
frequency range of 5 to 2000 MHz using miniature diode rings specially tailored
for high performance.
2. The package has been carefully designed for 50Ω systems to optimize RF
performance while achieving the small size and profile required of surface
mount devices. The Kovar input leads extend beyond the package wall to
facilitate inspection. In all units except the DMG-4B-1700, the internal
components and connections are compatible with IR and vapor phase mounting
of the device on a PCB. Hand soldering is required on the DMG-4B-1700.
3. Merrimac mixers comply with MIL-M-28837 and may be supplied screened
for compliance with additional specifications for military and space applications
requiring the highest reliability.
