Based on gallium-arsenide (GaN) technology, model BMPC9X89X8-8000 is a Class-AB solid-state pulsed power amplifier (PA) capable of 8 kW output power from 9.0 to 9.9 GHz. Designed for harsh environments, the rack-mount PA provides nominal gain of 69 dB and handles signals with pulse widths from 0.25 to 100.0 µs at 10% maximum duty cycle. The typical pulse rise/fall time is 50 ns. The rugged PA exhibits harmonics of −60 dBc and phase noise of −100 dBc/Hz offset 100 Hz from the carrier, with input/output VSWR of 1.50:1. It is equipped with female SMA connectors, Ethernet interface, and RS-422 differential control. The amplifier measures 19 × 12.25 × 24 in. and weighs 90 lb. It is designed for an ac voltage supply and operating temperatures from 0 to +50°C.

For truly high pulsed output power in radar applications, model 2185 is a rack-mount high-power amplifier (HPA) capable of 10 kW peak output power from 960 to 1,215 MHz. It features nominal gain of 74 dB and operates with pulse widths from 1 to 25 µs, duty cycles from 0.1 to 5.0%, and pulse repetition frequencies (PRFs) from 1 to 25 kHz. The robust HPA achieves its rated output power with input power levels of just −2 to +2 dBm. It exhibits low spurious levels, at typically −70 dBc, with second harmonics of nominally −12 dBc and third harmonics of nominally −16 dBc. The amplifier has built-in forced-air cooling along with a host of protection functions, such as input overdrive protection, output-power limiting, and thermal management. The flexible rack-mount amplifier is well-suited for radar component testing, research, and system development, as well as for tactical applications such as identify friend or foe (IFF), tactical air navigation (TACAN), and surveillance radar systems. It measures 19.00 × 5.25 × 22.00 in. and weighs 450 lb. It has a factory-configured serial RS-232 or RS422 interface and front-panel touchscreen display.

A line of waveguide bends includes models covering 12 frequency bands from 5.85 to 90 GHz (C-band to W-band frequencies). Available in waveguide sizes from WR-12 through WR-137, these bends are suitable for instrumentation, radar, satellite communications (satcom), and telecommunications systems in commercial and radar applications. They feature 90-deg. bends with VSWR as low as 1.08:1 and low insertion loss. The bends are constructed with gold-plated, oxygen-free hard copper (OFHC) or painted copper alloy, depending on the model. The bends are also offered with either a CPR-style flange or a UG-style flange per the military standard. Most models are RoHS-compliant. One of the waveguide bends, the WR-15 model SMF-15EB-001, operates from 50 to 75 GHz with worst-case VSWR of 1.10:1 and typical insertion loss of 0.17 dB.

Designed for use from 100 MHz to 3.8 GHz, model GRF6011 is a failsafe single-pole, double-throw (SPDT) switch well-suited for L-band satellite communications (satcom) applications. It is supplied in a miniature six-lead DFN-6 package measuring just 1.5 × 1.5 mm. It operates on a supply voltage of +3 to +5 V dc and a single control voltage of +3 V dc, drawing about 300 mA supply current. In switch mode, the component exhibits 0.33-dB insertion loss with 25-dB isolation. The 1-dB compression point is +20.5 dBm and the input third-order intercept point (IIP3) is +51 dBm. In failsafe mode, the insertion loss is 0.4 dB and the isolation is 22 dB. The 1-dB compression point is +29 dBm and the IIP3 is +49.5 dBm. The switch handles maximum input power to +36 dBm at operating temperatures from −40 to +105°C.

Limiter diodes in the SLP7100 series are fabricated from high-resistivity epitaxial wafers with thin intrinsic layers, and can be gold-doped for specific performance goals. The diodes, which can be used in circuits from 100 MHz to 30 GHz, are only 2 to 20 µm thick and can achieve turn-on times as fast as 5 ns. They exhibit low capacitance and resistance and are well-suited for protecting sensitive components from power surges or high-power signals, as might be encountered in radar and electronic-warfare (EW) systems. The diodes are available with maximum input-power-level ratings from +47 to +66 dBm and leakage power ratings from +19 to +44 dBm. The limiter diodes exhibit extremely low insertion loss, typically 0.1 to 0.2 dB.

In anticipation of the coming millimeter-wave backlinks in Fifth-Generation (5G) wireless networks, the model M60-3X2B frequency converter/mixer provides translation of V-band signals from 57 to 64 GHz. It works with a local-oscillator (LO) frequency range of 28.5 to 32.0 GHz (using an integral ×2 multiplier) and an intermediate-frequency (IF) range of 10 MHz to 7 GHz. Conversion loss is typically 6 dB and no more than 8.5 dB when fed with input signals at typically 0 dBm. The component draws 10-mA current from a -12-V dc supply. The unit is equipped with a female 2.92-mm coaxial connector on the RF and LO ports and a female SMA connector on the IF port, although the RF port can be configured in WR-15 waveguide. The frequency converter/mixer can be used for both upconversion and downconversion.
