DBM-184 DBM-184 Subminiature Flatpack Double Balanced Mixer 2MHz to 3000MHz DBM-184 is a high performance subminiature double balanced mixer utilizing precision matched beam-lead Schottky barrier diodes. The L port has a bandwidth of 2MHz to 3000MHz, while the R port covers 2MHz to 2500MHz, and the X port covers 5MHz to 1500MHz. Inputs to any two ports within their specified frequency range will produce the sum and difference frequency at the third port, with a minimum of undesired harmonic modulation products. The double balanced mixer may be used as an upconvertor, downconvertor, spectrum inverter or for any other frequency changing application. Other uses are as a phase detector, double sideband suppressed carrier modulator biphase modulator, pulse modulator, or frequency doubler. The combination of RFMD broadband transformer techniques plus the use of beam-lead Schottky barrier diodes achieve consistent low mixer noise figures and stable isolations. Precise transformer and diode balance provide two-tone third order IM ratios of better than 100dB with -30dBm input signals. Unique transformer design allows almost constant intermodulation suppression over the mixer’s entire operating frequency range. The subminiature package is sealed, RFI shielded and internally constructed to withstand severe environments. The device configuration allows convenient microstrip or printed circuit board mounting and the leads are easily soldered or welded.
