ti trf7900 receiver
Hi all
I need to build a 27MHz transceiver. I am now making the front-end.I got a few problems about the switch and antenna. The transceiver should be low cost and small,and operates at an indoor range of 30m.
My questions are
1) How could I design the circuit of the T/R...
27mhz antenna
I am going to make a antenna working at 27MHz, it will be a whip antenna,but i have no experience in doing so. I have many problems such as what kind of materials I should choose to make it, how can i make a shape of 'whip', how can i test if it is work or not? Could anyone give...
27mhz antenna
I am doing a 27MHz Antenna, it is on a transceiver,it will be a helical antenna and it should have a indoor operating range of 30m,how can i start my work?
thanks all
i have the problem in selecting the transistor in my LNA. i don't know which kind of transistor i should choose. My LNA is operating at 27MHz.
Is there any books that are good for beginners for designing LNAs?
As i am buidling a RF transceiver at 27MHz.
How can i start to design my LNA, for examples, how can i decide the LNA's parameter such as gain bandwidth, bias network, matching.........
I am going to build a 27MHz transceiver. I was required to design a low cost transceiver using FSK at 27MHz. This transceiver will need to be low cost, small and robust, with an indoor operating range of about 30m. This transceiver will incorporate for transmission an FSK modulator, low power...
