Product Description
The D602 is a SiGe divide-by-2 low noise static
prescaler capable of operation up to 6.0 GHz. The
D602 operates over a wide range of input frequencies
and levels, and provides differential outputs for low
noise operation with the common PLL style frequency
synthesizer ICs.
The static nature of the prescaler prevents spurious
generation.
The D602 prescaler can operate from either a single
positive or single negative supply with power down
mode for low standby power consumption.

Absolute Maximum Ratings
Operation in excess of any one of above Absolute Maximum Ratings may result in permanent damage. This device is
a high performance RF integrated and is ESD sensitive. The RF inputs on this device are Class 0 ESD rated;
therefore suitable precaution should be taken during handling, assembly and testing.

Notes: (1) Sample Tested
(2) For a sine-wave input
(3) Since the input signal is AC coupled, in the absence of an RF input, the prescaler may self oscillate and
provide an output at this frequency. Self oscillation can be eliminated by powering down the prescaler,
or applying a differential DC input voltage (a 47kΩ resistor placed between pin 3 and V
CC
).
(4) This power is delivered to a 50Ω load. It excludes the power dissipated in the external pull-up resistors.
