HMC948LP3E
v02.0913 POWER DETECTORS -SMT 54 dB, LOGARITHMIC
DETECTOR, 1 -23 GHz
Typical Applications Features The HMC948LP3E is ideal for: Wide Input Bandwidth: 1 to 23 GHz • Point-to-Point Microwave Radio Wide Dynamic Range: 54 dB up to 23 GHz • VSAT Single Positive Supply: +3.3V • Wideband Power Monitoring Excellent Stability Over Temperature • Receiver Signal Strength Indication (RSSI) Fast Rise / Fall Time: 5 / 7 ns • Test & Measurement 16 Lead 3x3 mm SMT Package: 9 mm² Functional Diagram General Description
The HMC948LP3E Logarithmic Detector converts
RF signals at its input, to a proportional DC voltage
at its output. The HMC948LP3E employs successive
compression topology which delivers high dynamic
range over a wide input frequency range. As the input
power is increased, successive amplifiers move into
saturation one by one creating an approximation of
the logarithm function. The output of a series of square
law detectors is summed, converted into the voltage
domain and buffered to drive the LOG OUT output.
The HMC948LP3E provides a nominal logarithmic
slope of +14.2 mV/dB and an intercept of -111 dBm at
23 GHz. Ideal as a log detector for high volume microwave radio and VSAT applications, the HMC948LP3E
is housed in a compact 3x3 mm RoHS compliant SMT
plastic package. Electrical Specifications, TA = +25 C Vcc = +3.3V
