1030/1090 MHz Pulsed IFF Power Amplifiers
Model: PA1033 / PA1105 / PA1123
WV Communications offers a line of 1030/1090MHz pulsed Identification Friend or Foe (IFF) power amplifiers:
- Model PA1033 — 3,200W
- Model PA1033-001 — 4,000W
- Model PA1105 — NEW: Dual 1,200W
- Model PA1123 — NEW: Dual 2,800W
PA1033 / PA1033-001
WV’s high-power IFF power amplifiers — the 3,200W Model PA1033 and 4,000W Model PA1033-001 — are used to transmit IFF long Mode 5 and Mode S 112-bit interrogation pulses, operating at Class AB. This compact package generates 3,200W / 4,000W minimum at the P1dB compression point (4,000 W / +66 dBm and 5,000 W / +67 dBm typical). The amplifiers have controlled response to 1090 MHz (-2 dB), enabling usage as Interrogator and Responder as necessary. Size is 9.50" × 6.87" × 4.40". The amplifier is built around a very-high-efficiency brazed heatsink, resulting in a small air-cooled package for easy thermal management.
A pulsed input of +10 dBm nominal produces an output level of +65 / +66 dBm. Output harmonic levels are low for the amount of power delivered to the load — the second harmonic is -40 dBc typical, while all other harmonics are less than -70 dBc. These amplifiers operate off +34 VDC, +12 VDC, and +5 VDC supplies. The maximum current on the +34 VDC supply is 6.0 / 8.0 amps under normal operating conditions. Input and output return loss is -20 dB typical.
PA1105 / PA1123 — Dual Amplifiers
WV’s newest amplifier models PA1105 and PA1123 are dual 1,200W and 2,800W amplifiers — compact, efficient models with specifications similar to the PA1033-XXX series above, operating off a +12 VDC supply. These models operate simultaneously in both SUM and SLS channels at all modes, including long Mode S and Mode 5.
