Description

1

VCC

Power-Supply Pin. Typical current consumption is 30 mA at room temperature. The VCC pin must be externally bypassed with a 100 nF

capacitor.

2

OUT

Detector Output. The DC voltage at the OUT pin varies linearly with the RF input power level in dBm. The detector output is able to drive a

50 Ω load. To avoid permanent damage, do not short to VCC or GND. In shutdown mode (EN = low), the detector output pin becomes high

impedance, to avoid discharge of capacitors in an external ripple filter.

3

FLTR

Filter. An optional capacitor connected between the FLTR pin and the OUT pin (Pin 2) reduces the detector ripple averaging bandwidth,

and increases the rise and fall times of the detector. To avoid permanent damage to the circuit, the DC voltage at the FLTR pin must not

exceed 0.4 V.

4, 5, 7

GND

Circuit Ground. All ground pins are internally connected. Pin 5 and Pin 7 must be used as RF return ground and connected to the

transmission line interfacing to the RFIN pin (Pin 6).

6

RFIN

RF Input. The RFIN pin is internally DC-coupled to the GND through a 50 Ω termination resistor. To avoid damage to the internal circuit, the

DC voltage applied to the RFIN pin must not exceed 1 V. The ground-signal-ground arrangement of Pin 5 through Pin 7 support termination

of Pin 6 by a high-frequency transmission line, such as a grounded co-planar waveguide (GCPW). No external decoupling capacitor is

necessary as long as the DC voltage on Pin 6 is kept below 1 V.

8

EN

Chip-Enable. A voltage above 1.1 V applied to the EN pin brings the device into normal operating mode. A voltage below 0.6 V brings the

device into a low-power shutdown mode. Do not float the EN pin.

EPAD

Exposed Pad. The exposed pad must be soldered to PCB ground .
