Temperature Sensor

Temperature Sensor Temperature Sensor electronic circuit The USB Humidity measures the relative humidity and air temperature though a hole in the middle of the housing. The device contains a calibrated precision sensor with a measurement accuracy of ±2 % relative humidity and ±0.4°C in most part of measurement range.The size of the device is about […]

Schematic Diagram hp – MAX2338 Mixer IF SAW Filter Match at 183.6MHz for CDMA

The design and simulation of the impedance match between the MAX2338 mixer stage and a 183.6MHz SAW filter in a CDMA application. The SAW filter S-parameter is used to simulate the interface with the mixer. A worked example is provided with a SAWTEK 855893 SAW filter. An optimum impedance matching circuit between the MAX2338 mixer […]
