SYM-30DMHW+ Level 13, SMT Double Balanced Mixer, RF/LO Freq 5 - 3000 MHz

Function

The SYM-30DMHW+ is a double-balanced mixer from Mini-Circuits, designed for RF and microwave signal processing. 

It efficiently combines or separates frequency components, making it essential in communication and signal conversion systems.

Key Features

• Frequency Range: Broadband operation, typically 5 MHz to 3000 MHz .

• Low Conversion Loss: ~6.5 dB (typical), ensuring minimal signal degradation during mixing .

• High Isolation:

  • LO-to-RF Isolation: ~36 dB (typical)

  • LO-to-IF Isolation: ~45 dB (typical) .

• Robust Construction: Compact, surface-mount design (likely TTT167 case, 6-pin) for integration into PCB-based systems .

• Power Handling: Supports 50 mW RF input power and operates at 40 mA current 

• Temperature Range:

  • Operating: -40°C to +85°C

  • Storage: -55°C to +100°C .

Typical Applications
