MAOC-009269-PKG003

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAOC-009269 is an InGaP HBT-based voltage controlled oscillator (VCO) operating from 11.4 GHz to 12.8 GHz. It features a divide-by-two output at 5.7–6.4 GHz and an integrated buffer amplifier. The device requires no external matching components and operates on a +5V bias supply. Key electrical specifications include a typical phase noise of -83 dBc/Hz at a 10 kHz offset, tuning sensitivity of 0.22 GHz/V, and a tune voltage range of 1 V to 13 V. It is housed in a lead-free 5 mm x 5 mm x 0.9 mm 32-lead PQFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number MAOC-009269 is available in tape and reel configurations (e.g., TR0500 for 500 pieces or TR1000 for 1000 pieces). Sample boards (SMB003) are also listed. Confirm RoHS compliance and 260°C reflow compatibility requirements during procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for applications requiring low phase noise and wide tuning ranges in the K/Ka-band spectrum. Ensure the design accommodates a +5V supply voltage and accounts for a total supply current of approximately 160 mA. The exposed pad must be connected to RF and DC ground to ensure proper thermal management and electrical performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This model belongs to the MACOM MAOC series of InGaP HBT voltage controlled oscillators. It shares architectural similarities with other models like the MAOC-009265 but targets higher frequency bands (11.4–12.8 GHz vs. 9.4–10.8 GHz). The family is characterized by integrated buffers and divide-by-two outputs for PLL integration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Designers should consult MACOM directly for alternative solutions or cross-reference based on specific frequency and phase noise requirements.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the function of Pin 12?

Pin 12 provides the divided-by-two (RF/2) output signal, operating in the frequency range of 5.7 GHz to 6.4 GHz.

How should the exposed pad on the package be handled?

The exposed pad centered on the package bottom must be connected to RF and DC ground. Connecting all N/C pins to RF/DC ground in the layout is also recommended.

What is the maximum supply voltage rating?

The absolute maximum supply voltage for both VCC and VBUFFER is +5.5 Vdc. Sustained operation near survivability limits is not recommended.
