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.
