Hi All: I been try to find a supplier for the TX2C And RX2C ICs. These are R/C toy car remote controller integrated chips. they are used in R/C cars brand names like nikko, radio shack, Bright lite , ect ect.. also been try to find there datasheets. does anybody know a website where i could get the TX2C and RX2C Datasheets. (Second Question). The TX2C chip thats in the r/c transmitter controller on pin-12osci and on pin-11osco I like to know the internal oscillator is set with a 200k ohm resistor and why they used 200k resistor and not a high or low resistor can you explain this to me that i could understand it. I can't post the circuit at this time. BUT you can see it at this site www.elenco.com/manuals/rcc-7k.pdf.. Can anybody who knows about R/C Electronics HELP ME. THANK YOU . Any help would be very Apprecited... :-[

Hi all: I just bought a R/C car kit to build and to learn about how they function. I been trying to find out in the output power stage of the amplifier Q2 in the circuit schematic. What is the output powerthat its set at. In milliwatts. to determine the maximum distance or range for output power, can I do this using OHMS-LAW to find this out,Or can anybody explain this to me in the most simplest form that i could uderstand. At this time i cannot post this schematic. BUT. the circuit can be SEEN at www.elenco.com/manuals/rcc-7k.pdf.. Can anybody who knows R/C Electronics HELP ME.. THANK you. PS any help would be apprecited... JJ.

Hi. MP Thanks for your help on these ICs. But unfortunately AD6411 I can't use. The MC13175 is Obsolete and the PBR941.This one would be to much design work for a Tx I want to design. IF you know of any other ICs please let me know. PS does any body know of more ICs I could use in my design. No Modules. just Tx ICc. Any more ICs you offer would be Appreciate. than you. cybertron.

Hi I'am try to find low cost ICs that i can use for my RF Transmitter design Iam transmitting in the UHF Frequencies between 300MHz to 480MHz bands i will be using 4to6 different frequencies in this range one will be 315MHz The rest not sure yet.SO I need to know who sell RF ICs, NO MODULES PLEASE.DOES ANYBODY HAVE OR KNOW OF ANY ICs THAT I CAN USE AND THERE PART NUMBERS AND THE MFDs names somebody must know some ICs i could use. power supply is +5V to +12V, low current high output between 200mW AND 800mW AND low frequency drift.the reason i don't want to use Modules is they are fixed at one set frequency some are more exspensive then others.and you can't replace a part you have to buy a new one went they don't work anymore.or even a stable UHF single transistors and be something i could use if you know of any in those frequencies. thank you for any help you have to offer. No schmatics.
