New MMIC VCOs are Ready for 5 GHz WLAN, VSAT and UNII Applications

Hittite Microwave has introduced two new MMIC VCOs for 5 GHz applica-tions: The HMC430LP4, covering 5.0 to 5.5. GHz; and the HMC431LP4, covering 5.5 to 6.1 GHz. Both devices are pro-vided in 4 x 4 mm plastic packages.The MMICs VCOs have on-chip resonators and do not require additional off-chip compo-nents other than bypass capacitors. The VCO output is AC coupled, requiring no additional coupling capacitors. The package has an exposed metal pad on the bottom to provide DC and RF grounding.
