TYPICAL APPLICATION
U
RF Field Detector
Figure 10 shows the complete circuit for a field detector
which was tested at 445MHz. A transmission line is used
to match the detector diode (1N5712) to a quarter-wave
whip antenna. The 0.23λ wavelength transmission line
section transforms the 1pF (350) diode junction capaci-
tance to a virtual short at the base of the antenna. At the
same time it converts the received antenna current to a
voltage loop at the diode, giving excellent sensitivity.

The rectified output is monitored by the LTC1540 com-
parator. The internal reference is used to set up a threshold
of about 18mV at the inverting input. A rising edge at the
comparator output triggers a one shot that temporarily
enables answer back and any other pulsed functions.
The total supply current is 400nA. Among other monolithic
one shots, the CD4047 draws the least amount of transient
current.
