Notes
1. Decreases 1.5 dB per octave.
2. fp = 349.25 MHz; Vp = 59 dBmV;
fq = 403.25 MHz; Vq = 59 dBmV;
measured at fp + fq = 752.5 MHz.
3. Measured according to DIN45004B:
fp = 341.25 MHz; Vp = Vo;
fq = 348.25 MHz; Vq = Vo −6 dB;
fr = 350.25 MHz; Vr = Vo −6 dB;
measured at fp + fq − fr = 339.25 MHz.
4. Measured according to DIN45004B:
fp = 851.25 MHz; Vp = Vo;
fq = 858.25 MHz; Vq = Vo −6 dB;
fr = 860.25 MHz; Vr = Vo −6 dB;
measured at fp + fq − fr = 849.25 MHz.
5. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.

Objective specification
This data sheet contains target or goal specifications for product development.
Preliminary specification
This data sheet contains preliminary data; supplementary data may be published later.
Product specification
This data sheet contains final product specifications.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
