Amplifiers and Oscillators

RSS

Amplifiers specific to the communications systems include a wide range of solid state power amplifiers (SSPAs) and low noise amplifiers (LNAs) originally from Paradise Datacom and a range organically developed product within TMS. Satcom SSPAs are considered a core competence of Paradise Datacom's product line who have invested heavily in converting it's complete amplifier offering from GaAs to GaN from C-Band all the way to Ka-Band.

Our range of low noise amplifiers (LNAs) cover a wide range of applications but are primarily suited to communication systems including both data-link and satellite communications (Satcom) systems. In recent years, LNA's have moved more and more into TMS's sweet spot, primarily due to the increase in operating frequency. For example, our new K-Band LNA operates over a 19.2 to 21.2 GHz with 1.3 dB noise figure at 25°C. It's configured with a waveguide input and 2.92 output connector all in a hermetic package.

TMS has built a strong portfolio of SSPAs covering 1 MHz to 110 GH and pulsed and CW power 1 W to 10 kW. TMS SSPAs are used in all markets, from commercial Satcom to military and space qualified platforms. TMS uses LDMOS, GaAs, InP and GaN technologies to meet customer's needs, generally producing custom designs to customer specifications. GaN is particularly successful in pulsed applications, with many different amplifier designs available up to 18 GHz.

Teledyne Microwave Solutions' Ka-band TWTA offers superior RF performance for the satellite uplink data communications market. In addition to its 502 W peak power, the amplifier features an integrated linearizer providing 175 W linear power at the output flange. Frequency ranges from 27.5 to 30.0 GHz for Commercial, or 30.0 to 31.0 GHz to accommodate military applications.

Richardson RFPD Inc. announced the availability and full design support capabilities for a new LDMOS integrated power amplifier from Freescale. The AFIC10275N is the industry’s first RF power integrated circuitcovering the 978-1090 MHz band. It integrates two amplification stages in a plastic package, delivering 250 W with 31 dB of gain and 64% drain efficiency. The device also embeds temperature and RF sensing capabilities, reducing the need for external components.

Linear Technology announces the LTC6268-10 single and dual LTC6269-10 4 GHz FET-input op amps for high dynamic range and high speed transimpedance amplifier (TIA) applications. The LTC6268-10 data sheet features example circuits ranging from 20 kΩ transimpedance gain at 210 MHz bandwidth, to 402 kΩ transimpedance gain at 34 MHz bandwidth. The LTC6268-10 is available in a 6-lead SOT-23 package, as well as an 8-lead SOIC with guard pins to protect against board leakage currents.

Linear Technology announces the LTC6268-10 single and dual LTC6269-10 4GHz FET-input op amps for high dynamic range and high speed transimpedance amplifier (TIA) applications.With 0.45pF input capacitance and 1000 V/µs slew rate, the LTC6268-10 and LTC6269-10 are well suited for photodiode and photomultiplier (PMT) circuits, high impedance sensor applications and for driving analog-to-digital converters (ADCs).
