Plastic SMT Schottky Mixer/Detector Diodes
Mon, 02/08/2010 - 7:30am
Aeroflex/Metelics introduces a family of surface mount GaAs and Silicon Schottky Mixer/Detector Diodes for high volume pick and place applications. These control devices are delivered in a plastic SMT package with standard 45 mils W X 75 mils L X 31 mils H dimensions. Their performance and mechanicals allow them to be easily dropped into existing designs. The family of detectors and mixers includes GaAs model SMGS11 which is appropriate for temperature compensation applications. This device operates at >26.5 GHz and features a min breakdown voltage of 5V, a typical capacitance of 0.10 pF and a max resistance of 7 ohms. The family also features GaAs model SMG21, which is an anti-parallel pair suited for use in doubler and harmonic mixer designs. SMG21 also operates at >26.5 GHz and offers a typical capacitance of 0.15 pF, a forward voltage min/max of 620/760 mV, and a max resistance of 7 ohms. Silicon zero bias Schottky diodes SMS201 and SMS202 are designed for broadband detector applications as they require no DC bias and offer excellent sensitivity of -54 dBm typical.
