Fixed Price Contracts
Wavemaker Technology Ltd can offer a contract for all types of projects and timescales. The contract big or small will deliver an extremely competative cost effective solution. Visible management will lead you through clear delierables with defined billing and payment cycles that are agreed at the start of any contract to match your program.

Typical Projects

• Researching new components, solutions and translating concepts into technical specifications
• Independent design reviews of RF and mmWave hardware
• Recommending an alternative for obsolete parts and designs
• Prototype testing and design validation
• Provide upgrade strategy in response to changing specifications
• Solving production design issues and implementing automated testing
• Subcircuit component design and simulation including MMIC layout and FPGA definition
• Full project implementation from concept to manufacture

Consultancy
Wavemaker Technology Ltd has over 40 years of design experience and is able to provide you with all the advice and help you need to achieve a successful outcome. Our aim is to build a strong client partnership offering hands-on experience, design skills and project management to provide a cost effective solution. An affordable and timely implementation will be achieved through integral proposal creation and progression through agreed project milestones.

Pmod Devices

---

Complementing the Digilent range of prototyping development accessories, Pmod products can interface to a wide range of Xilinx FPGA devices. Wavemaker Technology Ltd offer a range of Pmod development PCBs and RTL VHDL source code for quick integration into FPGA development module like the Digilant Basys 3.

GaN FET Half bridge
A single 3v3 logic input controls a half bridge configuration of two EPC2021 Gallium Nitride FETs. The Pmod PCB incorporates integral GaN drivers and high side power supply. Suitable for prototyping audio class D amplifiers or power supply switchers.

Audio A2D
A Texas Instruments PCM1804 audio analog to digital converter integrated with single ended to differential operational amplifier input buffer. This Pmod is setup to give 24 bit data quality of a four times over sampled audio signal for left and right channels. All converter parameters are selectable as is the interfacing configuration which can be set to I2C or DSP mode.

All pmod devices are £100
Price includes full documentation, VHDL source code and PCB schematics.

Reckoners & Calculators

---

Atten Pad calculator

• Attenuator Pad calculator, this table lists the E24 series resistor values required to make a "Tee" or "Pi" attenuator network. For each integer dB attenuator value in the range 1 to 20dB, the calculated loss is also provided

Phase Noise

• The A2D converter phase noise jitter clock reckoner. A graph of the phase noise required for a given signal to noise ratio and frequency. The plot axies are signal to noise resolution (converter effective number of bits) against the full scale sine wave frequency.

dBm Volts

• Calculator to convert dBm into watts, volts pk to pk and volts RMS
