What are the key features of HMC189AMS8ETR-AN?
- Passive frequency doubling from 2 GHz to 4 GHz input to 4 GHz to 8 GHz output with no DC bias required, eliminating power supply routing in microwave PCB layouts
- 8-lead MSOP SMT package enables compact placement in microwave signal chains alongside VCOs and amplifiers with standard 0.65 mm pitch footprint
- Broadband doubler architecture provides stable conversion over a 2-octave input bandwidth, reducing the need for multiple frequency-specific doublers in wideband designs
- Low fundamental and harmonic suppression suitable for frequency synthesis and LO generation in radar and communications systems up to 8 GHz
What is HMC189AMS8ETR-AN used for?
HMC189AMS8ETR-AN is used in microwave frequency synthesis chains for radar systems, satellite communications, and wireless test equipment where a 4 GHz to 8 GHz local oscillator signal must be derived from a lower-frequency VCO running at 2 GHz to 4 GHz. The passive doubler simplifies PLL-based synthesizer designs by halving the required VCO tuning range while maintaining phase noise performance. It is also used in point-to-point microwave links, SATCOM transceivers, and vector network analyzer front-ends requiring clean doubled-frequency references without active bias circuitry.

Frequently Asked Questions
What input and output frequency range does HMC189AMS8ETR-AN cover as a passive frequency doubler?
HMC189AMS8ETR-AN accepts input signals from 2 GHz to 4 GHz and produces a doubled output from 4 GHz to 8 GHz. This 2-octave input bandwidth allows a single part to serve multiple frequency plan variants in a radar or communications platform, reducing the number of unique RF components per design. The output frequency can be filtered to suppress residual fundamental and harmonic content for clean LO generation.
Does HMC189AMS8ETR-AN require DC bias and how does that simplify a radar front-end PCB layout?
HMC189AMS8ETR-AN is a passive doubler requiring no DC supply or bias voltage. Eliminating DC bias removes the need for bypass capacitors, bias resistors, and a dedicated supply trace on the RF PCB, which simplifies routing in dense microwave layouts where every millimeter of trace can affect impedance matching at 4 GHz to 8 GHz. The passive design also eliminates active-device noise contribution to the doubled output signal.
In a 5G mmWave test bench, why would HMC189AMS8ETR-AN in an 8-lead MSOP package be preferred over a waveguide doubler module?
HMC189AMS8ETR-AN in an 8-lead MSOP measures under 5 mm x 3 mm, fitting directly on a PCB signal chain next to the VCO and filter, whereas waveguide doubler modules typically measure 25 mm to 75 mm and require coaxial transitions. The SMT package reduces assembly time and signal path length at 4 GHz to 8 GHz, where every extra millimeter of coax introduces measurable insertion loss. For bench instruments needing repeatable, compact signal conditioning, the MSOP doubler lowers cost and module size simultaneously.
How does using HMC189AMS8ETR-AN halve the required VCO tuning range in a PLL-based 6 GHz synthesizer?
In a PLL targeting 5 GHz to 7 GHz output, using HMC189AMS8ETR-AN allows the VCO to operate at 2.5 GHz to 3.5 GHz — a 40% relative tuning range. Tuning a VCO over a 2-octave range at lower frequencies is easier to achieve with good phase noise than tuning directly at 5 GHz to 7 GHz. The doubler then multiplies both the frequency and the phase noise by 6 dB, but the improved low-frequency VCO noise floor typically results in a net phase noise improvement at the output compared to a direct 6 GHz VCO.
