Prescaler will operate down to D.C. for square-wave input signal. Minimum divide frequency limited by input slew-rate. Prescaler can exhibit this output signal under bias in the absence of an RF input signal. This condition can be eliminated by use of the Input DC offset technique described on page 3.

[2] 6-54 HMMC-3102/rev.3.3 Applications The HMMC-3102 is designed for use in high frequency communications, microwave instrumentation, and EW radar systems where low phase-noise PLL control circuitry or broad-band frequency translation is required. Operation The device is designed to operate when driven with either a singleended or differential sinusoidal input signal over a 200 MHz to 16 GHz bandwidth. Below 200 MHz the prescaler input is “slew-rate” limited, requiring fast rising and falling edge speeds to properly divide. The device will operate at frequencies down to DC when driven with a square-wave. Due to the presence of an off-chip RF-bypass capacitor inside the package (connected to the VCC contact on the device), and the unique design of the device itself, the component may be biased from either a single positive or single negative supply bias. The backside of the package is not DC connected to any DC bias point on the device. For positive supply operation, VCC pins are nominally biased at any voltage in the +4.5 to +6.5 volt range with pin 8 (VEE) grounded. For negative bias operation VCC pins are typically grounded and a negative voltage between -4.5 to 6.5 volts is applied to pin 8 (VEE). AC-Coupling and DCBlocking All RF ports are DC connected on-chip to the VCC contact through on-chip 50Ω resistors. Under any bias conditions where VCC is not DC grounded the RF ports should be AC coupled via series capacitors mounted on the PC-board at each RF port. Only under bias conditions where VCC is DC grounded (as is typical for negative bias supply operation) may the RF ports be direct coupled to adjacent circuitry or in some cases, such as level shifting to subsequent stages. In the latter case the package heat sink may be "floated" and bias applied as the difference between VCC and VEE. Input DC Offset If an RF signal with sufficient sig- VCC VCC IN ÷ IN nal to noise ratio is present at the RF input lead, the prescaler will operate and provide a divided output equal the input frequency divided by the divide modulus. Under certain "ideal" conditions where the input is well matched at the right input frequency, the component may "self-oscillate", especially under small signal input powers or with only noise present at the input This "self-oscillation" will produce a undesired output signal also known as a false trigger. To prevent false triggers or self-oscillation conditions, apply a 20 to 100 mV DC offset voltage between the RFin and RFin ports. This prevents noise or spurious low level signals from triggering the divider. Adding a 10KΩ resistor between the unused RF input to a contact point at the VEE potential will result in an offset of ≈ 25mV between the RF inputs. Note however, that the input sensitivity will be reduced slightly due to the presence of this offset.

For single-ended output operation the unused RF output lead should be terminated into 50Ω to a contact point at the VCC potential or to RF ground through a DC blocking capacitor. .GaAs MMICs are ESD sensitive.
