For sine–wave input signal. Prescaler will operate down to dc for square–wave input signal. Min. divide frequency limited by input slew rate. 2. 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 4. 3.

Square wave amplitude calculated from Pout. 3 Applications The HMMC-3124 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. 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). Operation The device is designed to operate when driven with either a single–ended or differential sinusoidal input signal over a 200 MHz to 12 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. ac–Coupling and dc–Blocking All RF ports are dc connected on–chip to the VCC contact through on–chip 50W resistors. Under any bias conditions where VC C 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. 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. VCC VCC 6 Input dc Offset If an RF signal with sufficient signal 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 an 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 RFi n and RFi n ports. This prevents noise or spurious low level signals from triggering the divider. Adding a 10KW 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.

Simplified Schematic 4 50 50 IN Vpwr sel Assembly Notes Independent of the bias applied to the package, the backside of the package should always be connected to both a good RF ground plane and a good thermal heat sinking region on the PC–board to optimize performance. For single–ended output operation the unused RF output lead should be terminated into 50W to a contact point at the VCC potential or to RF ground through a dc blocking capacitor. A minimum RF and thermal PC board contact area equal to or greater than 2.67 x 1.65 mm (0.105" x 0.065") with eight 0.020" diameter plated–wall thermal vias is recommended.
