NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. Dimensions marked with * apply only at body.
4. All unmarked pins are case ground.
General Notes:
1. The DMH-4R-1000 Double Balanced Mixer covers the frequency band
of 10 to 2500 MHz using two parallel ring modulators to produce a wide
bandwidth circuit with very low intermodulation. This mixer is ideal for
cellular radio receiver systems. Although designed for drive levels of +13
dBm, it operates well at drive levels ranging from +7 to +17 dBm.
2. This mixer is provided in a half relay package that may be mounted
directly to the PCB. In situations where component height is a constraint,
the leads may be conformally formed allowing the package to be soldered
flush to the PCB.
3. Merrimac mixers comply with MIL-M-28837 and may supplied screened
for compliance with additional specifications for military and space
applications requiring the highest reliability.
