Looking for the cheapest method to commincate in 433MHz

hello

I am looking for a transmiter and a receiver in 433Mhz with a
cheap way.

I do not need hi speed.

 

[BlackOps]

microchip

i am also looking for them, created the thread:


and here is the store where i suggest you to buy it:

https://futurlec.com/Radio.shtml

it is very cheap online shop, i did buy things from them. and the delivery is just 5$

 

[drewcam888]

saw filter 433 cheap

I used one of there products and wasn't very pleased. It didn't to perform as well as expected.

regen transmitter

Probably not cheapest, but good performance, based on Chipcon/TI-IC

tire pressure monitoring (tpm) system microchip

i am looking not only for modules but for ic like chipcon

does anyone use CC1100?
or does anyone use RFPIC12F275?

 

[Sadegh.j]

vco bfr93

Search for a transceiver in this frequency, it should be easy to find. From what I know, hopeRF, wavecom and SIM are quiet cheap.

where to buy rfpic12f675f

i am looking not only for modules but for ic like chipcon

does anyone use CC1100?
or does anyone use RFPIC12F275?

what is your problem with this PIC ?
can explain it

433mhz multichannel transmitter

Is this for mass production ?. If so I can help !. I designed a 433 MHz receiver for some 19 USD cent ! Transmitter is a little more 50 cnt USD.

transmitter bfr93

PaulHolland it is for mass production,

can you send me your designs?

i do not have any problem with microchip but
i did not use it yet.

Have you use it

nrf401

Does anyone have a schematic with Rfpic12f675F with FSK modulation

 

[armixic]

433 mhz regenerativ receiver

cc1100 is a good choice. Also, accel semiconductor has AS6801 transceiver can work at 433MHz.

 

[PaulHolland]

ad7020 datasheet

How much does the AS6801 cost and you have a datasheet ?.

For rfPIC16F675F look here:

AN238 - Tire Pressure Monitoring (TPM) System (microchip website)

[FvM]

cheapest transceiver 433 mhz

As a basic design decision, you should know if you need multi-channel capability. Then only synthesizer based transceivers, e. g. Chipcon are to choose from, rfPIC would be excluded. Said AS6801 has audio features, wouldn't expect it as a candidate for basic data communication, unless it has an extraordinary pleasant price.

 

[raduga_in]

nRF 401 FSK transciver seems to be good for
that ..

[blapcb]

nRF401 is a dead product. You have to look at nRF905

 

[satish.e.86]

check wit tws434 n rws434 ics

 

[rogerynt]

Use super-regenerative method with an op huplse shaper at demodulation out.

 

[chrismicro]

Look here **broken link removed** for the RR4 Receiver module at $6.95 USD a transmitter is also listed for $5.95 but I can help you with a diagram and outlay using a BFR93 transistor and a 433 SAW filter, note the outlay is very important to limit harmonics, if I can help PM me and I will upload the goodies

Hi

Try Analog Device family
AD7020-1
Almost Everything on-chip!

y can do a vco as the transmitter,maybe this is the cheapest bu the performance is poor, or y can choose the NRF403 as the transceiver of the 433M
