DBM-143 Subminiature Flatpack Double Balanced Mixer 10MHz to 1500MHz RFMD Model DBM-143 is a high performance subminiature double balanced mixer utilizing precision matched beam-lead Schottky barrier diodes. The L and R ports have a bandwidth of 10MHz to 1500MHz while the X port covers a bandwidth of DC to 1000MHz. 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 up convertor, down convertor, spectrum inverter or for any other frequency changing application. Other uses are as phase detector, double sideband suppressed carrier modulator, bi-phase modulator, pulse modulator or a 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 80dB with -30 dBm 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.
