Recently we have received customer development request, for making a customized lift control, which controls the movement of industrial lift, using either manual button or wireless remote. To test and verify our receiver hardware and software design, we have built a small elevator model, as in following photo. Also you can check out our video …

For typical keyfob driven by SAW resonator, the high quality usually means optimised for best frequency stability, fast startup time and ghost-less working, which will greatly affect actual working distance. The first point, best frequency stability, is achieved when local LC network’s actual working frequency is a little more than desired frequency, and drifts SAW …

Which frequency should I use when planning to design a RF (Radio Frequency) product in the United States? 315MHz is primarily used for remote key less entry (RKE) systems and garage door openers. As a result, this frequency is somewhat crowded, increasing the chances for interference. The FCC allowed power is lower than 418MHz or …

Here we picked some commony asked questions by customers, regarding RF remote control transmitters and receivers, and we hope it will help our customer choose the suitable product, thanks. 1. Can multiple remote control transmitters be used nearby to each other? Many times designers assume that because a transmitter has a unique address code or …

Here we write down some frequently asked questions regarding FCC ID test and certificate, hope it will help customer in FCC testing process. 1. How much does FCC certificate test cost? This depends on how much you have the test lab do. Full transmitter and receiver testing can cost around $5,000, transmitter only around $3,500, …

Follow-up on previous post, we have prepared the sample and send 1pcs working sample to testing labs on Jun 27th, 2014 and the testing labs received sample on Jun 28th, 2014. The testing labs checked the sample and confirmed it would work fine in following test, the test sample is 1pcs 315Mhz remote control transmitter …

Today we received a customer enquiry, asking if our default remote control transmitter can be hard-wired to be integrated into other system, the detail listed as follows. Customer ask, can the transmitter / remote control be hard-wired for intergation with another system? such as a honeywell fault signal, not sure if this is pulsed, or …
