Analog Devices confirms that its parts are used in Lekha Wireless’s 4G RAN reference design, and its product directory lists a Lekha Himalia radio card featuring the AD9375 transceiver. Those records establish a technical relationship, but they do not identify the ADI part or Lekha product involved in the specific 5G-and-4G integration described in the headline.
What is confirmed about the Lekha–Analog Devices relationship?
Analog Devices’ partner directory lists Lekha Wireless as a partner since 2017 and says Lekha’s 4G RAN reference design uses ADI parts. The reference design includes hardware and software stacks for LTE user equipment (UE) and eNodeB products. The directory does not name the parts or identify revisions.

Separately, ADI lists a Lekha Himalia radio card featuring its AD9375. This is evidence of a named Lekha design using that transceiver; it does not establish that the AD9375 is used across Lekha’s current product range or in the particular integration referenced by the headline.

What’s actually slowing this PC down?

What does the AD9375 do?
ADI describes the AD9375 as an “Integrated, Dual RF Transceiver with Observation Path.” Its listed applications include 3G/4G small-cell base stations and massive-MIMO or active-antenna systems. That makes the part relevant technical context for radio access network equipment, but the application list is not proof of deployment in a particular Lekha product.
#1 Best Overall
- nRF24L01 is a single chip radio transceiver for the worldwide 2.4 - 2.5 GHz ISM band. Compatible with Arduino and Raspberry Pi
- Applications: Wireless peripherals, remote control systems such as RC vehicles and consumer remote electronics, wireless voice transmission such as VoIP, wireless sensor networks, wireless networks, home and commercial automation
- Ultra Small: 15x29mm (including: built-in 2.4GHz antenna), for easy implementation into designs without additional hardware
- Auto-acknowledge and auto-retransmit function
- You can find several resources available online easily, such as tutorials, data sheets, and notes
ADI also offers the ADRV9375-N/PCBZ and ADRV9375-W/PCBZ, which it describes as 2×2 radio evaluation cards for prototyping and evaluating AD9375-based radio solutions. These are evaluation products, not evidence that a Lekha commercial system uses either card. ADRV9375-N/PCBZ · ADRV9375-W/PCBZ
Which Lekha products are in scope?
Lekha’s public portfolio describes several relevant product areas, but the available product descriptions do not map a named ADI part to a current SKU:
Rank #2
- 433mhz RF Transmitter and Receiver Superheterodyne UHF ASK Remote Control Switch Module For Arduino Wireless Diy Kit.
- Mains input voltage range: 2.2V-5V; Operating frequency: 433.92 MHz, bandwidth of about ± 150KHz.
- Low-power performance, along with high dynamic range (greater than 60dB). Module uses highly integrated chip, built front-end low-noise amplifier,Mixers, filters, frequency synthesizer circuit, etc., can maximize the signal optimization.
- Support ASK / OOK modulation, the receiver sensitivity of -108dBm.
- Applications: Can be used for wireless power switch, socket, remote control switch, receiver module, smart home products, remote control curtains, remote MP3, and so on.
- Vyapi LTE eNodeB: Lekha describes support for multiple TDD and FDD bands and radio front ends for listed LTE bands.
- Vyapi LTE Network-in-a-Box: Lekha describes a system combining RAN, EPC and compute.
- 5G Open RAN: Lekha’s mobile-network portfolio includes 5G Open RAN products.
These descriptions provide product context only; they do not establish that any of these current offerings uses the AD9375 or another specific ADI part. Lekha Wireless products · Lekha Wireless mobile networks

A C-DOT release dated 31 July 2023 names Lekha among the companies in a consortium developing an O-RAN-compliant, disaggregated 5G RAN solution intended to operate in FR1 and FR2. This documents 5G development context, but it does not connect that project to ADI technology or identify an ADI component. C-DOT consortium release, 31 July 2023
Rank #3
- HiLetgo 4pcs NRF24L01+ Wireless Transceiver Module
- Multi-frequency: 125 frequency points
- Low operating voltage : 1.9 ~ 3.6V low voltage operation
What remains unconfirmed?
The cited public material does not specify which ADI parts are used in the integration described by the headline, which current Lekha 4G or 5G products use them, or whether the integration is shipping. It also does not establish launch timing, customer deployments, supported bands, or performance attributable to this integration. The Himalia/AD9375 listing is a documented example, not a substitute for those missing product-level details.
