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 bi-
phase 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.
