Overview
The HMC598 is an x2 active broadband frequency multiplier chip manufactured by Analog Devices Inc. utilizing GaAs PHEMT technology. Designed for VSAT applications, it operates within a frequency range of 22 GHz to 46 GHz at the output. When driven by a +5 dBm input signal, the device provides a typical output power of +15 dBm. The component features isolation between the fundamental frequency (Fo) and third harmonic (3Fo) of 25 dB at 30 GHz. It is supplied as a bare die in bulk packaging.
Feature Summary
- Utilizes GaAs PHEMT technology for high-performance RF multiplication
- Provides active x2 frequency multiplication across a wide bandwidth
- Delivers high output power when driven by standard input levels
Applications
- VSAT communication systems
- DBS receiver front-ends
- Millimeter-wave signal generation chains
Procurement Notes
Verify current availability status as supply may be limited or discontinued. Confirm that the specific ordering suffix matches the required die configuration. Ensure compatibility with existing GaAs MMIC handling procedures due to the bare die format. Check for any specific environmental compliance requirements such as RoHS3 status before integration into final designs.
Selection Notes
Select this component for applications requiring wideband x2 multiplication in the Ka-band range. Consider the +5 dBm drive requirement and resulting +15 dBm output power when designing the preceding amplifier stage. Evaluate the need for Fo and 3Fo isolation performance at 30 GHz relative to system noise floor requirements. Assess thermal management capabilities suitable for bare die mounting on substrates.
Part Context
The HMC598 belongs to the family of GaAs MMIC frequency multipliers from Analog Devices. It serves as a compact solution for generating higher frequency signals from lower frequency sources. The bare die format allows for flexible integration into custom microwave assemblies and hybrid modules where space constraints are critical.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if alternative models within the same manufacturer's portfolio offer similar frequency ranges and output power specifications.
