Hi Zack,
Target region for 433 MHz SubGHz is China and we are using SmartRF Studio.
Here are some results from first proto measured from balun output before switch. I have tried much more but not recorded all the measurement results because no improvement…
Does the frequency of 915 MHz and 868 MHz can pass Asia Telecommunications regulations (China, Japan, Korea)?
Do I just setup the frequency range and tx power to meet the regulations?
Hi Ofer,
Our most up-to-date preliminary designs have been developed for a 0201 component size (see Section 2.4 of SWRA814 ( SimpleLink CC131x and CC135x Family Hardware Migration Guide ) https://www.ti.com/lit/swra814 for reasons this could result in performance…
The following ref. designs for CC1101 are availabe:
CC1101EM JTI Balun 868/915 MHz
CC1101EM 868-915MHz
CC1101EM 434 MHz
CC1101-CC1190EM 915 MHz
RF3858-CC1101
We do not have any reference code for this protocol.

This is a custom board and I started by selecting CC1352P7_4 Launchpad as my base not knowing that the 868 band (915 MHz) is not supported. The problem didn't become apparent until I checked the High PA box. I made a new project using CC1352P7_1 Launchpad…
The sub-1 PHYs supported can be found in smartrf studio:
For sub1 PHY for 802.15.4, you can also refer to the ti154stack examples:
(in the project's .syscfg file: "RF STACKS" --> "TI 15.4 STACK" --> Radio)
The GFSK PHY…
Hi, we have followed the CC1101EM 868 – 915 MHz Reference Design (swrr045.zip) Here's the oscillogram after a manual power reset. Prescaled clock signals in antiphase immediately appear on GDO0 and GDO2 pins.
Moreover, we are not able to reproduce…
HSM (4 Mbps) is only supported in the 868 and 915 MHz bands. Settings are provided in rfPacketErrorRate example in the simplelink_cc13x0_sdk_4_20_02_07 SDK.

Hi Sabari,
The CC1190 can only be used for 868/915 MHz operation, so a 433 MHz matching network is not possible.
The factors discussed in Section 9 of SWRA640 is applicable to any of our Wireless Connectivity devices, including the CC1120, but the target…
Hi Ito,
Please provide the following information to assist with this:
Is the target frequency still 868/915 MHz?
Is the RGZ or RSK device being used for the design?
Following on from the previous question, which reference design was followed?
Are the…
