What is a transceiver?
How often we asked for this question? It’s a word composed by the two : trans-mitter and receiver.
Together they do TRANS-CEIVER. It’s a device that can both transmit and receive communications, in particular a combined radio transmitter and receiver. A receiver can only receive and a transmitter can only transmit. The term originated in the early 1920s.
The term transceiver for Ham Radio user is quite common. But in the general communication (Engineering) we can also distinguish SFT module (Small-Factor Pluggable) – particular connector optic fibers, Ethernet and SONET.
The SFP has replaced the GBIC connector, which has the big advantage to be little.
Standard velocities of SFP are 155Mbps, 622Mbps, 1Gbps, 1.25Gbps, 2.5Gbps, 3Gbps, 4.25Gbps, 10Gbps (SFP+) e 25Gbps (SFP28). Maximul distance tested are 220m, 300m, 2km, 10km, 20km, 40km, 60km, 80km, 100km, 120km e 150km.
The XFP transceiver indeed (10 Gigabit Small Form Factor Pluggable) is another connector which use only optic fibers.
What is a transceiver in the HAM RADIO World.
It’s a device which cost several hundreds of $$$ which is able to transmit and receive. You obviously need a good Antenna to transmit the signl over the space. HF is the frequency of transmission. High Frequency ( 0 – 30 Mhz ).
The transceiver is made of transistors, condensators and resistors. Inside you will find two or three motherboards which are able to receive and make possibile the transmission. The best companies in the world that produce and sell these HF transceivers are: KENWOOD, YAESU, ELECRAFT, ICOM.
If you are looking indeed for a transceiver HF VHF UHF : here is the answer. Yaesu FT 857.
I would also recommend the YAESU FT 817 ND – very compact transceiver. These two are the best transceiver HF VHF UHF. But what does a HF VHF UHF means? Quite simple: it’s a transceiver able to transmit on these 3 bands (0-30 HF, 144-146 VHF, 430 – 440 UHF)!
Which are the best amateur radio stores in the world?
Well, if you ask which are the amateur radio stores it’s quite hard to list here all of them.
In Europe for sure the WIMO (wimo.de) it’s the best ham radio store where you can all the transceivers available on the market. In USA indeed the best amateur radio stores are the
hamradiooutlet.com and the gigaparts.com. Remember always to get in touch with these amateur radio stores via email / ask any info you like.
Looking for SDR Transceivers?
There is no yaesu sdr transceiver. There is no Kenwood sdr transceiver. There is no ICom SDR transceiver. Yes , these companies do not produce SDR transceiver. Quite a shame I would say.
What’s a SDR transceiver? SDR stands for sofware defined radio (SDR). It’s a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. I suggest you also to visit these links, especially if you’re looking for a kit.
Transceiver meaning ?
Quite easy. As said before: the transceiver meaning is a device able to transmit and receive on the same frequency in different modes : SSB (USB, LSB), AM, FM, CW. There are also digital modes like FT8. So the transceiver meaning for ham radio users is the following: ability to speak, to talk to many other people for free. Just experiment! Try your best antenna, test your transceiver.
What’s an optical transceiver? It’s this pictured below!
Well, quite different. Isn’t it? The optical transceiver is a device able to assure the communication between different devices at data-rate of 100G/ 40G/ 10G/ 8G/ 6G/ 4G/ 3G Video/ PON / 2.5G/ 2.125G/ 1.25G/ 622M/ 155M/100Mbps network. The optical transceiver uses fiber optical technology to send and receive data. The transceiver has electronic components to condition and encode/decode data into light pulses and then send them to the other end as electrical signals. To send data as light, it uses light source, which is controlled by the electronic parts, and to receive light pulses, it makes use of a photodiode semiconductor. Quite simple isn’t it?
The optical transceiver is completely different from a SDR transceiver.
