Teledyne Microwave Solutions (TMS) has extensive experience in the design and manufacture of detector log video amplifiers (DLVAs). These devices are used extensively in applications requiring an output voltage related to the power of a received RF signal. In order to cope with a wide range of input signals a log amplifier is used to provide a linear voltage output per dBm of input power.

Teledyne Microwave Solutions (TMS) offer a range of Limiting Amplifiers which are used in instantaneous frequency and phase measurement receivers. The most important performance requirement of a limiting amplifier is to minimize output power variations, and provide a constant output over a wide input dynamic range.

Gain Shape amplifiers are used in a number of applications where it's necessary to flatten the gain characteristic of the preceding or following component. This would include flattening the attenuation of a long cable run or perhaps changing the input gain response to a MPM (Microwave Power Module) or TWT (Traveling Wave Tube) to compensate for the gain variation within the tube.

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 discrete GaN on SiC HEMT from TriQuint / Qorvo. The 30 W (P3 dB) TGF3021-SM operates from 0.03 to 4.0 GHz and is constructed with TriQuint’s TQGaN25 production process, which features advanced field plate techniques to optimize power and efficiency at high drain bias operating conditions.

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.
