Coral RF: Multiband Radio Receiver Semiconductor Modules for IoT and Telemetry

Coral RF is a global supplier of high‑performance multiband radio receiver semiconductor modules, specializing in Sub‑1GHz and 2.4GHz wireless solutions based on leading chipsets from Texas Instruments, Semtech, and Silicon Labs. Their products serve as the core building blocks for IoT devices, smart metering, remote control, telemetry, and industrial automation.

What Are Multiband Radio Receiver Semiconductor Modules?

Multiband radio receiver semiconductor modules integrate one or more RF transceivers, matching networks, and often a microcontroller into a compact package. They can receive (and transmit) signals across multiple frequency bands – for example 433 MHz, 868 MHz, 915 MHz, and 2.4 GHz – within a single module. This eliminates the need for separate radio front‑ends for each band, saving board space, power, and development time. Coral RF’s modules are true multiband solutions: they support global ISM bands, regional smart metering bands (e.g. China 470‑510 MHz), and even 169 MHz for wireless M‑Bus.

Core Product Families

Sub‑1GHz Multiband Receiver Modules

Coral RF offers a wide range of Sub‑1GHz modules based on TI’s CC13xx series and CC11xx transceivers, as well as Semtech’s LoRa devices.

All these modules act as multiband radio receiver semiconductor modules – they can be programmed to receive (and transmit) on different frequency bands by simply changing the firmware and external matching components. For example, the N530AS can be configured for 433 MHz (China/Europe), 868 MHz (Europe), or 915 MHz (North America) on the same hardware.

2.4 GHz & Zigbee Modules

For 2.4 GHz applications, Coral RF provides Zigbee modules based on TI’s CC2538 and CC2652.

These modules integrate a multiband radio receiver (2.4 GHz ISM band) with a powerful ARM Cortex‑M3, making them ideal for mesh networking, smart home, and building automation.

USB Dongles – Multiband Receiver Tools

Coral RF offers USB dongles that function as multiband radio receiver semiconductor modules for testing, gateways, and field commissioning.

• N534BP (CC1312R): +14 dBm, supports 433/868/915/1200 MHz

• N537BP (CC1312R+PA): +27 dBm, for 868/915 MHz

• N710AP (CC2538+CC2592): +22 dBm, Zigbee 3.0 USB dongle with Raspberry Pi support

These dongles can act as portable spectrum sniffers, gateway adapters, or development tools. They are pre‑loaded with firmware that allows host control via AT commands, making them plug‑and‑play multiband receivers for PC‑based IoT applications.
