Our comparison chart shows that WyJen Technologies offers high performance digital ASK RF modules that outperform its competitors in simplicity, greater receiver sensitivity, higher bit rate verses cost, lower power consumption as a result of power up/down modes, and available VHDL codes for reducing development costs.

Cost vs. bit rate

We offer better cost verse high bit rate for our solutions which means more flexibility in your design process.  The greater the bit rate the greater the use of your design for other applications such as voice, data transfer, and networking, etc.  Low data rate transmitters and receivers are typically employed in nominal applications such as toys that do not require low power consumption, high data rates and improved operating/transmission efficiencies.

Low power Consumption

We offer power on and power off modes for our transmitters and receivers with lower power down currents.  This means lower power consumption and longer battery life for your products. This is an especially important requirement for battery powered portable products. 

Simplicity

Our products offer simplicity. The minimum required interface is simply one data input for the transmitter and one data output for the receiver along with power and ground. This allows fast turn around for a digital wireline transmission system that wants to become wireless, just replace the wire with a transmitter and its corresponding receiver, and your system is wireless. Our transmitter use popular operating input voltages such as 3.3V and 5V and no glue logic. This also means that our modules can easily be integrated into an existing system with minimum effort and low cost. At the same time we also offer flexibility for more advanced systems, if you desire to interface your wireless system to a digital signal processor (DSP) or programmable logic device (PLD) we can provide some initial code such as VHDL for free. 

Reduced Development Costs

When available we offer a standard VHDL code for our transmitters and receivers interfaces which mean less development costs and more profit.  The VHDL code is available for customers who which to employ a programmable logic device as the means of control to supplement the surrounding glue logic.  Our devices can also be easily incorporated in an existing wireline system which consists of a cable interface between the transmitting source and the receiving source.  The replacement of the cable interface with a wireless interface using our transmitter and receiver combination requires minimum or no RF knowledge.

Greater Sensitivity

We offer greater sensitivity for our receivers (-115dBm) which means the ability to detect a RF signal from the transmitter at longer distances.  A larger negative value translates into greater sensitivity of the receiver. Thus -115dBm is much more sensitive than a device that is -102dBm.  The sensitivity of a receiver is the minimum RF signal that can be detected at the receiver and demodulated.  This results in improved transmission distance.  The best way to increase the sensitivity is to reduce the noise level in the receiver.  Thus, our receiver consists of a low noise amplifier that increases noise reduction. 

Why Use Digital Over Analog Modulation

It is also important to know when to use digital verse analog modulation in your products.  If your products require security of data, use digital modulation such as amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK), quadrature phase shift keying (QPSK), etc. as these methods allow techniques to easily encode the transmitter and decode the data at the receiver without expensive circuitry.  ASK is sometimes referred to as On Off Shift Keying (OOK).  Amplitude modulation (AM) and frequency modulation (FM) are examples of analog modulation methods.
