Texas Instruments acquired all of Radia Communications in July 2003 for approximately $133 million, according to TI’s SEC filing. The Sunnyvale company brought expertise in 802.11 wireless networking and multi-band, multi-mode radios. TI said the deal would expand its radio-frequency (RF) semiconductor and related technology offerings.
What did Radia Communications make?
Radia was a Sunnyvale-based RF chip and design company focused on 802.11 wireless local-area networking (WLAN) and multi-band, multi-mode radios. Those capabilities covered radio-frequency semiconductors and related subsystems, signal processing, and networking technologies for WLAN products.
The available accounts do not identify Radia’s exact chip models or part numbers. They describe its technology area, not a complete product catalog.
Why did Texas Instruments buy Radia?
TI said it wanted to broaden its RF semiconductor, subsystem, signal-processing, and networking offerings. Bringing Radia’s RF products and engineering expertise in-house was intended to support TI’s integration efforts. Joseph Crupi, then TI vice president and general manager of the Broadband Communications Group, said: “Having increased RF product offerings and engineering expertise in-house will accelerate our integration momentum.”
#1 Best Overall
- 【Wideband Low Noise Amplifier – 0.1-2000MHz Coverage】This RF amplifier operates from 0.1MHz to 2000MHz, covering shortwave, FM broadcast, VHF/UHF, and even 2G/3G/4G signals. Perfect for ham radio, SDR, CB radio, and remote control receivers
- 【32dB Gain & Low Noise Figure】With a typical gain of 32dB and a low noise figure, this LNA (low noise amplifier) significantly improves weak signal reception. The maximum output is 13dBm (20mW) at 50 ohm system impedance, ideal for RF receiving front‑end applications
- 【9-12V DC Operation – Battery Friendly】Supports 9V to 12V power supply (e.g., lithium batteries) with only 27mA current consumption. Works as a portable low noise amplifier for field use, or fixed installation with a 12V wall adapter
- 【Versatile for Many Applications】Use it as a CB amplifier, radio frequency amplifier for FM radios, signal booster for TV antennas, or as a wideband preamp for spectrum analyzers and test equipment. Also suitable for cable TV signal amplifiers and remote control receivers
- 【Stable & Reliable Performance】Built with wide frequency range, high gain, and consistent 50 ohm impedance. This RF wideband amplifier helps increase communication distance and improve reception quality in weak signal environments. Great for DIY projects, amateur radio, and shortwave listening
The deal therefore added wireless-radio capability to TI’s portfolio; the cited disclosures do not establish a specific product launch or quantify the acquisition’s later commercial results.
How much did TI pay, and what did the accounting show?
TI’s 2003 Form 10-Q says it acquired 100% of Radia in July 2003 for approximately $133 million. The contemporaneous EE Times report, published July 30, said the terms had not been disclosed publicly at that time; the later SEC filing provides the purchase-price figure.
Rank #2
- Ultra‑Broadband LNA Module: Frequency range:100kHz‑10GHz; Gain:21.5dB@10MHz / 21dB@2GHz /17.5dB@6GHz, OP1dB:13dBm Typ. Low‑noise, good flatness. Can replace ADM‑8095 modules
- USB‑Interface Powered: USB‑powered low noise pre‑amplifier, supply current 52mA. On‑chip bias solution. You can adjust bias resistor to reduce working current for different usage scenarios
- Great Noise‑Floor Improvement: Built‑in high‑PSRR LDO suppresses power‑supply noise. Obvious noise‑floor improvement compared with regular USB powered LNA modules on market
- TinySA ULTRA High‑Frequency Test: Ideal external preamplifier for TinySA‑ULTRA. Native onboard LNA only performs well below 3.5GHz. ZK09‑UM improves high‑band receiving & measuring performance
- Safety & Environmental Tips: Compact shielded metal housing. Never apply excessive input power, otherwise saturation or permanent damage may occur. Prevent damp environment to avoid metal shell rust for outdoor applications

Radia’s operations were integrated into TI’s Broadband Communications Group as Texas Instruments Sunnyvale Inc. EE Times reported that Radia had approximately 50 employees at the time. The available sources do not establish a later standalone Radia business, a surviving Radia-branded product line, or current availability of its original chips.
Rank #3
- PCB adopts 1.6mm thick double‑sided board, full tinning process, ensures good passing of large and small currents.
- Manufactured according to the original production specifications, in line with strict quality standards.
- Professional RF amplifier module, features 1‑930MHz working frequency, stable performance.
- Large heat dissipation area can better maintain long‑term operation, not easy to be damaged.
