Antenna Design as simple as never before.
With our Rapid Antenna Prototyping Tool, antenna development has never been easier.
QUARTERWAVE offer two types of solutions. A quick solution with off-the-shelf antennas, or a custom-made antenna tailored to your product.
Two Paths to One Solution
Customer Benefit
Best Performance
QUARTERWAVE extracts the last dB of performance from off-the-shelf antennas and, furthermore, provides custom-made antennas with the best possible performance.
Reduce time to maket
Speed up your product development with a shorter design cycle through end-to-end antenna devolopment, including precompliance measurement.
Reduce costs
No expensive equipement, no antenna expertise and no expensive simulation tools required.
Reliable partner
Consistency, Dependability, Open Communications, Problem-Solving and Long-Term Commitment distinguishes QUARTERWAVE.
TX prototype for wireless microphone system:
QUARTERWAVE developed the RF frontend of a digital wireless microphone system.
Unlike traditional analog wireless microphone systems, which use analog radio frequency (RF) signals, digital wireless systems convert audio signals into digital data for transmission. This technology is commonly used in various applications, including live performances, public speaking events, broadcasting, and recording studios.
LATEST DEVELOPMENTS
ETSI mask measurement according EN 300 422-1:
Unintended emissions from the transmitter in the out-of-band domain refer to frequencies just outside the operational channel, arising from the modulation process but excluding spurious emissions. To verify that the transmitter operates exclusively within the designated channel, we assessed the output spectrum using EN 300 422-1 guidelines and adhered to the defined ETSI mask limits.
Analysis of digital modulations:
Quarterwave can even examine complex digital modulations down to the symbol level. Therefore Quarterwave uses the latest tools to evaluate signal quality using constellation and eye diagrams.
In the example, a PI/4 DQPSK modulated signal with a bandwidth of 150kHz was analysed to evaluate whether the I/Q modulator of the RF frontend of the transmitter is working properly.
TECHNOLOGY EXPERT
As experts in cutting-edge technologies within radio engineering and antenna design, our primary emphasis is on tailoring solutions to meet the specific needs of our clients. As your dedicated partner, we provide consultation and precompliance measurments on radio solutions for product approvals. Everything you need comes from one hand: from the initial feasibility study to product design, and from development through to series production. Moreover, we guarantee that your products undergo certification in adherence to international regulatory guidelines.
