Both Winterflood and Oriel rate the trust as a "buy", ranking it above its main rivals Herald and Polar Capital.
The £109m trust offers investors a good way to get access to the exciting new developments on the US west coast, the brokers say.
Tom Tuite Dalton, analyst at Oriel Securities, said: "The trust has tended to have a significantly higher-than-benchmark allocation to high-growth mid cap companies that RCM considers to be the emerging leaders in the technology sector.
"It believes that the successful identification of these companies early on in their growth stages offers the best opportunity for outperformance over the long-term."
The manager, Walter Price, has headed up the portfolio since 2007 but has been running technology funds since 1985. He is based in Silicon Valley, the heart of the US technology world, which analysts from both Winterflood and Oriel cite as a key advantage.
It has certainly been a successful few years for the trust, which has returned 105.25 per cent over the past half-decade in share price terms, according to data from FE Analytics.
This compares with growth of 80.32 per cent from the FTSE World Technology index. The fund is benchmarked against the Dow Jones World Technology index, which is not included on FE Analytics.

In the short-term, its performance has also been impressive, judging by the half-yearly figures published last week.
In the six months to 31 May, the fund’s NAV has increased by 27.3 per cent, compared with benchmark returns of just 15.8 per cent.
One of the reasons for this outperformance has been the weakness of sterling relative to the dollar, which means that all of the trust’s investments held in the US currency have grown in value.
Many commentators think that the strength of the dollar could be one of the dominant themes of the next few years, meaning this advantage is set to become greater still.

Price is happy to take big bets away from his benchmark, such as holding just 0.2 per cent of his fund in Apple. This decision proved to be a major driver of performance – while other funds took a hit when the tech behemoth started to tumble, RCM was relatively unaffected.
RCM started reducing its position in Apple in the third quarter of 2012, and shares subsequently declined on concerns about its ability to produce successful new products.
The trust prefers to hold firms such as Tesla Motors – at 5.3 per cent of AUM – which develops electric cars.
"Part of the strategy is to invest in companies that use technology in an innovative way to gain a strategic, competitive edge," Tuite Dalton said.
"Tesla Motors falls within this category and during the period, the electric vehicle and powertrain manufacturer was among the largest contributors to active returns (that is to say fund returns less benchmark returns), with its share price increasing by 189 per cent."
"Tesla's shares appreciated after reporting that it sold more Model S sedans during fiscal Q1 than previously forecast."
"The company also announced that unit sales increases had helped it reach the first quarterly profit in its history as a public company."
RCM Technology Trust's largest position is in Google, at 6.3 per cent of AUM. Amazon is another top-10 holding, making up 2.1 per cent of the portfolio.
The trust is positioning itself to benefit from what it sees as secular growth trends in areas such as cloud computing, infrastructure upgrades and mobile phone apps.
The managers also say that US business outlay on IT is set to increase, with many companies having delayed spending during the long downturn.
Winterflood points out that the trust is cheaper than its peers.
According to AIC figures, it is currently trading on a discount of 9.16 per cent, meaning that investors pay 9.16 per cent less for a share of the company than they would for the relevant underlying holdings.
This is slightly more expensive than its one-year average of 10.28 per cent, but only marginally off its three-year average of 9.11 per cent.
This compares with a 2.2 per cent discount for Polar Capital Technology.
Polar Capital Technology also has a strong track record, having made 141.07 per cent over five years, but has been eclipsed in the short-term by RCM, according to Tuite Dalton.
Its NAV lagged the DJ World Technology index in the year to 31 May and it has suffered from having a larger weighting to Apple than RCM.
Tuite Dalton says that the only reason why he would not recommend it is that there are cheaper options elsewhere, and notes that as a larger trust – with a £548m market cap – it has greater liquidity.
The other cheaper option in the sector is Herald, which invests across communications and multimedia companies, as well as technology.
The £437m trust is largely UK-focused, and Tuite Dalton says that investors should not be too quick to overlook it.
Chip-maker Imagination Technologies, at 2.7 per cent of assets, is the trust’s largest holding, and it also holds stocks in the media sector, such as M&C Saatchi and Euromoney.
"Although Herald Investment Trust’s performance in recent months can best be described as dull, some will recognise and appreciate the fact that Herald is effectively providing much-needed capital to the UK’s high-tech growth companies," Tuite Dalton said.
"Note also that its long-term NAV total return is well ahead of its peers'. On a 19 per cent discount to NAV and with some £350m (approximately 60 per cent of net assets) invested in UK tech companies, a holding in Herald would complement a holding in RTT in our view."
"The former benefits from its UK presence, while the latter benefits from being headquartered in Silicon Valley."
Data from FE Analytics shows that Herald has made 90.44 per cent in share price terms over five years and 47.67 per cent over three.
The trust is sitting on a discount of 20.5 per cent, according to the AIC, and has ongoing charges of 1.07 per cent.
RCM Technology has ongoing charges of 1.21 per cent inclusive of a performance fee, while Polar Capital Technology charges 1.22 per cent, again inclusive of a performance fee.
