General Description
The HMC561 is a x2 active broadband frequency multiplier chip utilizing GaAs PHEMT technology. When driven by a +5 dBm signal, the multiplier provides +17 dBm typical output power from 8 to 21 GHz and the Fo and 3Fo isolations are 15 dBc at 16 GHz. The HMC561 is ideal for use in LO multiplier chains for Pt to Pt & VSAT Radios yielding reduced parts count vs. traditional approaches. The low additive SSB Phase Noise of -139 dBc/Hz at 100 kHz offset helps maintain good system noise performance.

Features
• High Output Power: +17 dBm
• Low Input Power Drive: 0 to +6 dBm
• Fo Isolation: 15 dBc @ Fout= 16 GHz
• 100 KHz SSB Phase Noise: -139 dBc/Hz
• Die Size: 1.6 x 0.9 x 0.1 mm

Typical Applications
The HMC561 is suitable for:
• Clock Generation Applications: SONET OC-192 & SDH STM-64
• Point-to-Point & VSAT Radios
• Test Instrumentation
• Military & Space
