2 Radio Frequency Stocks to Watch From a Prospering Industry

The Radio Frequency (RF) semiconductor industry, despite recent underperformance against broader markets and macroeconomic headwinds, is poised for bullish near-term growth, driven by the adoption of WiFi 7, 5G, edge IoT, AI data centers, and automotive electrification, as evidenced by a 5.2% rise in 2025 earnings estimates. While trading at a lower forward P/E of 14.76x, key players like RF Industries (RFIL) are seeing strong share appreciation and backlog growth, while Skyworks (SWKS) anticipates Q1 FY26 revenues of $975M-$1.025B, benefiting from broad market expansion despite mobile segment weakness.

Analysis

The Zacks Semiconductors - Radio Frequency (RF) industry demonstrates bullish near-term prospects, supported by a Zacks Industry Rank #9 (top 4%) and a 5.2% increase in 2025 earnings estimates since January. Key growth drivers include accelerated 5G deployment, the continued adoption of WiFi 7, and the rapid proliferation of edge IoT, AI data centers, and automotive electrification, with the EV market projected to quadruple by 2027. These trends underscore a robust demand for advanced RF content and connectivity solutions.

Despite these tailwinds, the industry faces significant headwinds, including a challenging demand environment, inventory buildup, sluggish capital spending by telecom carriers, and heightened global macroeconomic uncertainties. Weakness in end-markets such as automotive, industrial, and infrastructure is also a concern. The industry has underperformed over the past year, declining 7.8% compared to the S&P 500's 14.4% gain and the broader sector's 24.4% appreciation.

However, the industry's current forward 12-month P/E ratio of 14.76x is notably lower than the S&P 500's 23.3x and the broader sector's 28.61x, suggesting a potential undervaluation relative to its growth potential. This valuation metric, coupled with a median P/E of 15.02x over the past five years, indicates that current pricing is near the lower end of its historical range.

RF Industries (RFIL), a Zacks Rank #1 (Strong Buy), has seen its shares surge 75.5% over the past year, driven by a growing backlog of $19.7 million at the end of Q3 2025 and an expanding footprint across diverse customer segments. Skyworks (SWKS), a Zacks Rank #3 (Hold), benefits from demand in automotive electrification, edge IoT, and AI data centers, projecting Q1 FY26 revenues between $975 million and $1.025 billion, with broad markets growing mid-to-high single digits. However, SWKS anticipates a low to mid-single-digit sequential decline in its Mobile segment and faces macroeconomic and tariff challenges, contributing to its 20.6% share drop over the past year.

Key Decisions for Investors

• Investors should consider the long-term structural growth drivers within the RF semiconductor industry, such as 5G, IoT, AI, and EV adoption, despite current macroeconomic and inventory-related challenges.
• RF Industries (RFIL) presents a strong growth profile with significant recent share appreciation and backlog expansion, warranting further due diligence for potential long positions.
• Skyworks (SWKS) offers exposure to key secular growth trends but faces mobile segment weakness and broader macroeconomic pressures, suggesting a more cautious or hold approach until clearer signs of segment recovery or macro stabilization emerge.
