DF782_PHA-1H+_FINALThe Big Deal

  • Ultra High IP3
  • Broadband High Dynamic Range without external Matching Components
  • Operates to 105°C
  • May be used as a replacement to WJ AH1a,b

Product Overview

PHA-1H+ (RoHS compliant) is an advanced wideband amplifier fabricated using E-PHEMT technology and offers extremely high dynamic range over a broad frequency range and with low noise figure. In addition, the PHA-1H+, unlike competitive models, has good input and output return loss over a broad frequency range without the need for external matching components and has demonstrated excellent reliability. Lead finish is SnAgNi. It has repeatable performance from lot to lot and is enclosed in a SOT-89 package for very good thermal performance.

 Key Features



Broad Band: 0.05 to 6.0 GHz

Broadband covering primary wireless communications bands:

Cellular, PCS, LTE, WiMAX

Extremely High IP3

Versus DC power Consumption

40.4 dBm typical at 2.4 GHz

The PHA-1H+ matches industry leading IP3 performance relative to device size and power consumption. The combination of the design and E-PHEMT Structure provides enhanced linearity over a broad frequency range as evidence in the IP3 being typically 20 dB above the P 1dB point. This feature makes this amplifier ideal for use in:

• Driver amplifiers for complex waveform up converter paths

• Drivers in linearized transmit systems

• Secondary amplifiers in ultra High Dynamic range receivers

No External Matching Components Required

Unlike competing products, Mini-Circuits PHA-1H+ provides Input and Output Return Loss of 10-23 dB up to 4 GHz without the need for any external matching components

Low Noise Figure: 2.6dB typ. up to 4 GHz

3.4dB typ. up to 6 GHz

A unique feature of the PHA-1H+ which separates this design from all competitors is the low noise figure performance in combination with the high dynamic range.

Low Juction Temperature

Tj=115°C at 85°C lead temperature and 135°C at 105°C lead temperature

Results in excellent reliability.






















a. Suitability for model replacement within a particular system must be determined by and is solely the responsibility of the customer based on, among other things, electrical performance criteria, stimulus conditions, application, compatibility with other components and environmental conditions and stresses.

b. The WJ AH1 part number is used for identification and comparison purposes only.
