AMR: Automated Meter Reading
Passive Line Component Offering
AMR is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (water, gas, and electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. AMR technologies include handheld, mobile and network technologies based on telephony platforms (wired and wireless), radio frequency (RF), or power line transmission. [1]
Radio frequency based AMR are commonly allocated in a handheld, mobile, and fixed network. There are both two-way RF systems and one-way RF systems in use that use both licensed and unlicensed RF bands such as ISM that use different protocols such as Zigbee. The following frequencies are those that Johanson has focused on their development to cater wireless AMR applications:
- 915MHz (US)
- 2.45GHz (US, Europe, and Asia)
- 868GHz (Europe)

Capacitors, MLCC
R05S, R07S, and R14S – Series: These lines of multilayer Hi-Q capacitors have been developed for High-Q low–loss wireless applications. These MLCC’s are ideal for impedance matching, decoupling, and further discrete filtering when needed.
For more information visit our Multi-Layer High-Q Capacitors page.
Inductors, Ceramic and Wirewound
L-05, L07, and L15 – B, C, and W Series: These two series offer a mid Q and High-Q solution depending on filtering needs or spurious emissions optimization.
