Ka-Band Power Amplifier Module
MITEQ Inc. introduces a new addition to its family of broadband high power amplifiers, Model AMF-8F-27003150-55-30P. This compact amplifier is a connectorized high power gain module, covering SATCOM bands 27 to 31.5 GHz and delivering approximately 1W of power. High thermal performance housing is 0.37” (9.3 mm) high, 1” (25.5 mm) long (without connectors) and 0.83” (21 mm) wide (without the DC pins). Total length including the field-replaceable 2.92 mm K-connectors is 1.76” exactly.

Nominal small-signal gain of the amplifier is 35 dB minimum, ±1.5 dB, while noise figure is close to 4.5 dB typical. Port VSWRs are less than 2.3:1. Minimum P1dB is 30 dBm. Output IP3 is a minimum of 33 dBm and a typical of 37 dBm across the full band.

It is intended for bolting to a flat cooling surface. Housing can be hermetically or environmentally sealed.

Regulation and bias sequencing is internal, so only a single +10 to +15V supply is required. Typical current draw is near 1.2A linear and about 1.7A at full power. Operational from –40 to +85°C base plate temperature, with about 1 dB degradation in power and gain.

Isolator protected at both the pressure-sealed WR-42 waveguide input and K(F) connector output, the low-noise amplifier is lightweight and has a small profile and footprint. The aluminum alloy housing is environmentally sealed and also fully EMI shielded. LNA includes reverse voltage, over current and over temperature protection in addition to full internal regulation. Total weight is approximately 800 grams, and dimensions are 156mm x 70mm x 51mm.

The AMFW-8F-17702130-120-23P-WP has a typical noise temperature of 110°K, with a maximum of 120°K, and it is capable of a minimum of 23 dBm of P1dB across the full band, 17.7 to 21.3 GHz. Output IP3 is 33 dBm minimum.

Input and output port VSWR is a maximum of 1.25:1 and 1.5:1 respectively. Small-signal gain is 62dB and flatness is 2dB peak-to-peak maximum. Maximum ripple is 0.2 dB/40 MHz within the whole band. Gain variation with temperature is less than 0.08 dB/°C. Gain is stable too less than 0.4 dB/Month. Total group delay is constant to less than 1 nsec over the full band. Current draw is nominally 400 mA from a single +12V to 24V supply. Other voltage ranges and alarm options are available. Operating temperature –40 to +70°C case.

2W Millimeter-Wave Power Amplifier
MITEQ introduces a new addition to its family of high frequency, high power amplifiers. Model AMF-5B-33003500-80-32P is a connectorized high power amplifier/module, covering 33-35 GHz and delivering approximately 2.5W of saturated power and 2W of P1dB over a 2 GHz band. The connectorized Aluminum alloy housing is 19 mm high, 76 mm long and 89 mm wide. Connectors are female, K-type. It is intended for bolting to a flat cooling surface.

Nominal small-signal gain is over 50 dB. Noise figure is nominally 6 dB. Output VWSR is a maximum of 2.3:1 and input is 2:1 maximum. Output P1dB is 32 dBm minimum and 33 dBm typical. Current draw is nominally 2.2A at P1dB. This module has an internal regulator and operates from a single 12-15V and it also has reverse and thermal protection. A TTL pin gives control over bias turn on/off. Operating temperature range is -40° to +55°C base plate.

This power amplifier can be supplied on a custom heatsink if required.
