hi everyone
i'm working on a project which needs Uart Data Transmission
i used Hm-T FSK module!have you ever used this module?in my country hm-t is the most popular FSK module for Uart Linking
in order to achieve a higher range i chose BGY204 UHF Amp made by Philips company
you can see the Datasheet's link below
http://www.datasheetcatalog.org/datasheet/philips/BGY204.pdf
here,on page 7 there is a test circuit!please take a look at the circuit
all the components are clear but:
1.what's the L1 inductor?is it a prepared inductor that i must buy it?possibly,is it important to assemble it or not?
2.what's the ZL and Zs? is it necessary to attend to ZL Zs striplines calctulation if i use this pcb?
3.can i use carbonized resistor instead of Metal film resistor?
4.I think ZL,Zs stripline acts as an inductor in transmitters,is it correct?
thanks for your regard
