NOTES: Care must be taken not to power up the device with pins 7 and 8 shorted by a solder bridge, as operation with pin 7 grounded can damage
the device and result in low sensitivity.

Notes:
1. Sensitivity is defined as the minimum average signal level measured at the input necessary to achieve a bit error ratio of
10
-2
where the input signal is a return to zero pulse (RZ) with an average duty cycle of 50%. The RF input is assumed to
be matched into 50
.
Measured in test circuit Fig. 6 with data filter bandwidth of 5KHz as shown and for a 2Kbit/s, 50% duty cycle signal.
2. Signal handling is defined as the maximum input signal capable of being succcessfully de-modulated. It is assumed the
input is ASK modulated with an extinction ratio of a least 40dB. The combination of this specification together with the
sensitivity specification gives a minimum signal handling range of 76dB. The RF input is assumed to be matched into 50
.
Measured in test circuit Fig. 6. with data filter bandwidth of 5KHz as shown.
3. -67dBm in 50
measured with the RF input matching network.
4. Adjacent channel rejection is defined for an interfering tone (ACR) dB above threshold and 10MHz offset from the carrier giving a 3dB
reduction in sensitivity i.e. the interfering tone is 4.74mV (rms) @ Fc
±
10MHz and to achieve the specified sensitivity the wanted signal
will have to be increased to 2.2
μ
V (rms)
5. Please refer to Smith charts Fig.8 through to 10 covering frequency range 250-500MHz.
